In physics, energy () is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

The total energy contained in an object is identified with its mass, and energy (like mass), cannot be created or destroyed. When matter (ordinary material particles) is changed into energy (such as energy of motion, or into radiation), the mass of the system does not change through the transformation process. However, there may be mechanistic limits as to how much of the matter in an object may be changed into other types of energy and thus into work, on other systems. Energy, like mass, is a scalar physical quantity. In the International System of Units (SI), energy is measured in joules, but in many fields other units, such as kilowatt-hours and kilocalories, are customary. All of these units translate to units of work, which is always defined in terms of forces and the distances that the forces act through.

A system can transfer energy to another system by simply transferring matter to it (since matter is equivalent to energy, in accordance with its mass). However, when energy is transferred by means other than matter-transfer, the transfer produces changes in the second system, as a result of work done on it. This work manifests itself as the effect of force(s) applied through distances within the target system. For example, a system can emit energy to another by transferring (radiating) electromagnetic energy, but this creates forces upon the particles that absorb the radiation. Similarly, a system may transfer energy to another by physically impacting it, but that case the energy of motion in an object, called kinetic energy, results in forces acting over distances (new energy) to appear in another object that is struck. Transfer of thermal energy by heat occurs by both of these mechanisms: heat can be transferred by electromagnetic radiation, or by physical contact in which direct particle-particle impacts transfer kinetic energy.

Energy may be stored in systems without being present as matter, or as kinetic or electromagnetic energy. Stored energy is created whenever a particle has been moved through a field it interacts with (requiring a force to do so), but the energy to accomplish this is stored as a new position of the particles in the field—a configuration that must be "held" or fixed by a different type of force (otherwise, the new configuration would resolve itself by the field pushing or pulling the particle back toward its previous position). This type of energy "stored" by force-fields and particles that have been forced into a new physical configuration in the field by doing work on them by another system, is referred to as potential energy. A simple example of potential energy is the work needed to lift an object in a gravity field, up to a support. Each of the basic forces of nature is associated with a different type of potential energy, and all types of potential energy (like all other types of energy) appears as system mass, whenever present. For example, a compressed spring will be slightly more massive than before it was compressed. Likewise, whenever energy is transferred between systems by any mechanism, an associated mass is transferred with it.

Any form of energy may be transformed into another form. For example, all types of potential energy are converted into kinetic energy when the objects are given freedom to move to different position (as for example, when an object falls off a support). When energy is in a form other than thermal energy, it may be transformed with good or even perfect efficiency, to any other type of energy, including electricity or production of new particles of matter. With thermal energy, however, there are often limits to the efficiency of the conversion to other forms of energy, as described by the second law of thermodynamics.

In all such energy transformation processes, the total energy remains the same, and a transfer of energy from one system to another, results in a loss to compensate for any gain. This principle, the conservation of energy, was first postulated in the early 19th century, and applies to any isolated system. According to Noether's theorem, the conservation of energy is a consequence of the fact that the laws of physics do not change over time.

Although the total energy of a system does not change with time, its value may depend on the frame of reference. For example, a seated passenger in a moving airplane has zero kinetic energy relative to the airplane, but non-zero kinetic energy (and higher total energy) relative to the Earth.

History

The word ''energy'' derives from the Greek '''', which possibly appears for the first time in the work of Aristotle in the 4th century BC.

The concept of energy emerged out of the idea of ''vis viva'' (living force), which Gottfried Leibniz defined as the product of the mass of an object and its velocity squared; he believed that total ''vis viva'' was conserved. To account for slowing due to friction, Leibniz theorized that thermal energy consisted of the random motion of the constituent parts of matter, a view shared by Isaac Newton, although it would be more than a century until this was generally accepted. In 1807, Thomas Young was possibly the first to use the term "energy" instead of ''vis viva'', in its modern sense. Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term "potential energy". It was argued for some years whether energy was a substance (the caloric) or merely a physical quantity, such as momentum.

William Thomson (Lord Kelvin) amalgamated all of these laws into the laws of thermodynamics, which aided in the rapid development of explanations of chemical processes by Rudolf Clausius, Josiah Willard Gibbs, and Walther Nernst. It also led to a mathematical formulation of the concept of entropy by Clausius and to the introduction of laws of radiant energy by Jožef Stefan.

During a 1961 lecture for undergraduate students at the California Institute of Technology, Richard Feynman, a celebrated physics teacher and Nobel Laureate, said this about the concept of energy:

Since 1918 it has been known that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time. That is, energy is conserved because the laws of physics do not distinguish between different instants of time (see Noether's theorem).

Energy in various contexts

The concept of energy and its transformations is useful in explaining and predicting most natural phenomena. The ''direction'' of transformations in energy (what kind of energy is transformed to what other kind) is often described by entropy (equal energy spread among all available degrees of freedom) considerations, as in practice all energy transformations are permitted on a small scale, but certain larger transformations are not permitted because it is statistically unlikely that energy or matter will randomly move into more concentrated forms or smaller spaces.

The concept of energy is widespread in all sciences. In the context of chemistry, energy is an attribute of a substance as a consequence of its atomic, molecular or aggregate structure. Since a chemical transformation is accompanied by a change in one or more of these kinds of structure, it is invariably accompanied by an increase or decrease of energy of the substances involved. Some energy is transferred between the surroundings and the reactants of the reaction in the form of heat or light; thus the products of a reaction may have more or less energy than the reactants. A reaction is said to be exergonic if the final state is lower on the energy scale than the initial state; in the case of endergonic reactions the situation is the reverse. Chemical reactions are invariably not possible unless the reactants surmount an energy barrier known as the activation energy. The ''speed'' of a chemical reaction (at given temperature ''T'') is related to the activation energy ''E'', by the Boltzmann's population factor e^{−''E''/''kT''}that is the probability of molecule to have energy greater than or equal to ''E'' at the given temperature ''T''. This exponential dependence of a reaction rate on temperature is known as the Arrhenius equation.The activation energy necessary for a chemical reaction can be in the form of thermal energy. In biology, energy is an attribute of all biological systems from the biosphere to the smallest living organism. Within an organism it is responsible for growth and development of a biological cell or an organelle of a biological organism. Energy is thus often said to be stored by cells in the structures of molecules of substances such as carbohydrates (including sugars), lipids, and proteins, which release energy when reacted with oxygen in respiration. In human terms, the human equivalent (H-e) (Human energy conversion) indicates, for a given amount of energy expenditure, the relative quantity of energy needed for human metabolism, assuming an average human energy expenditure of 12,500kJ per day and a basal metabolic rate of 80 watts. For example, if our bodies run (on average) at 80 watts, then a light bulb running at 100 watts is running at 1.25 human equivalents (100 ÷ 80) i.e. 1.25 H-e. For a difficult task of only a few seconds' duration, a person can put out thousands of watts, many times the 746 watts in one official horsepower. For tasks lasting a few minutes, a fit human can generate perhaps 1,000 watts. For an activity that must be sustained for an hour, output drops to around 300; for an activity kept up all day, 150 watts is about the maximum. The human equivalent assists understanding of energy flows in physical and biological systems by expressing energy units in human terms: it provides a “feel” for the use of a given amount of energy In geology, continental drift, mountain ranges, volcanoes, and earthquakes are phenomena that can be explained in terms of energy transformations in the Earth's interior., while meteorological phenomena like wind, rain, hail, snow, lightning, tornadoes and hurricanes, are all a result of energy transformations brought about by solar energy on the atmosphere of the planet Earth.

In cosmology and astronomy the phenomena of stars, nova, supernova, quasars and gamma ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen).

Energy transformations in the universe over time are characterized by various kinds of potential energy that has been available since the Big Bang, later being "released" (transformed to more active types of energy such as kinetic or radiant energy), when a triggering mechanism is available.

Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. This energy is triggered and released in nuclear fission bombs. In a slower process, radioactive decay of these atoms in the core of the Earth releases heat. This thermal energy drives plate tectonics and may lift mountains, via orogenesis. This slow lifting represents a kind of gravitational potential energy storage of the thermal energy, which may be later released to active kinetic energy in landslides, after a triggering event. Earthquakes also release stored elastic potential energy in rocks, a store that has been produced ultimately from the same radioactive heat sources. Thus, according to present understanding, familiar events such as landslides and earthquakes release energy that has been stored as potential energy in the Earth's gravitational field or elastic strain (mechanical potential energy) in rocks. Prior to this, they represent release of energy that has been stored in heavy atoms since the collapse of long-destroyed supernova stars created these atoms.

In another similar chain of transformations beginning at the dawn of the universe, nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang. At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight. Such sunlight from our Sun may again be stored as gravitational potential energy after it strikes the Earth, as (for example) water evaporates from oceans and is deposited upon mountains (where, after being released at a hydroelectric dam, it can be used to drive turbines or generators to produce electricity). Sunlight also drives many weather phenomena, save those generated by volcanic events. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, give up some of their thermal energy suddenly to power a few days of violent air movement. Sunlight is also captured by plants as ''chemical potential energy'' in photosynthesis, when carbon dioxide and water (two low-energy compounds) are converted into the high-energy compounds carbohydrates, lipids, and proteins. Plants also release oxygen during photosynthesis, which is utilized by living organisms as an electron acceptor, to release the energy of carbohydrates, lipids, and proteins. Release of the energy stored during photosynthesis as heat or light may be triggered suddenly by a spark, in a forest fire, or it may be made available more slowly for animal or human metabolism, when these molecules are ingested, and catabolism is triggered by enzyme action.

Through all of these transformation chains, potential energy stored at the time of the Big Bang is later released by intermediate events, sometimes being stored in a number of ways over time between releases, as more active energy. In all these events, one kind of energy is converted to other types of energy, including heat.

Distinction between energy and power

Although in everyday usage the terms ''energy'' and ''power'' are essentially synonyms, scientists and engineers distinguish between them. In its technical sense, power is not at all the same as energy, but is the rate at which energy is converted (or, equivalently, at which work is performed). Thus a hydroelectric plant, by allowing the water above the dam to pass through turbines, converts the water's potential energy into kinetic energy and ultimately into electric energy, whereas the amount of electric energy that is generated per unit of time is the electric power generated.

Conservation of energy

Energy is subject to the law of conservation of energy. According to this law, energy can neither be created (produced) nor destroyed by itself. It can only be transformed.

Most kinds of energy (with gravitational energy being a notable exception) are subject to strict local conservation laws as well. In this case, energy can only be exchanged between adjacent regions of space, and all observers agree as to the volumetric density of energy in any given space. There is also a global law of conservation of energy, stating that the total energy of the universe cannot change; this is a corollary of the local law, but not vice versa. Conservation of energy is the mathematical consequence of translational symmetry of time (that is, the indistinguishability of time intervals taken at different time) - see Noether's theorem.

According to energy conservation law the total inflow of energy into a system must equal the total outflow of energy from the system, plus the change in the energy contained within the system.

This law is a fundamental principle of physics. It follows from the translational symmetry of time, a property of most phenomena below the cosmic scale that makes them independent of their locations on the time coordinate. Put differently, yesterday, today, and tomorrow are physically indistinguishable.

This is because energy is the quantity which is canonical conjugate to time. This mathematical entanglement of energy and time also results in the uncertainty principle - it is impossible to define the exact amount of energy during any definite time interval. The uncertainty principle should not be confused with energy conservation - rather it provides mathematical limits to which energy can in principle be defined and measured.

In quantum mechanics energy is expressed using the Hamiltonian operator. On any time scales, the uncertainty in the energy is by

: $\backslash Delta\; E\; \backslash Delta\; t\; \backslash ge\; \backslash frac\; \{\; \backslash hbar\; \}\; \{2\; \}$

which is similar in form to the Heisenberg uncertainty principle (but not really mathematically equivalent thereto, since ''H'' and ''t'' are not dynamically conjugate variables, neither in classical nor in quantum mechanics).

In particle physics, this inequality permits a qualitative understanding of virtual particles which carry momentum, exchange by which and with real particles, is responsible for the creation of all known fundamental forces (more accurately known as fundamental interactions). Virtual photons (which are simply lowest quantum mechanical energy state of photons) are also responsible for electrostatic interaction between electric charges (which results in Coulomb law), for spontaneous radiative decay of exited atomic and nuclear states, for the Casimir force, for van der Waals bond forces and some other observable phenomena.

Applications of the concept of energy

Energy is subject to a strict global conservation law; that is, whenever one measures (or calculates) the total energy of a system of particles whose interactions do not depend explicitly on time, it is found that the total energy of the system always remains constant.

The total energy of a system can be subdivided and classified in various ways. For example, it is sometimes convenient to distinguish potential energy (which is a function of coordinates only) from kinetic energy (which is a function of coordinate time derivatives only). It may also be convenient to distinguish gravitational energy, electric energy, thermal energy, and other forms. These classifications overlap; for instance, thermal energy usually consists partly of kinetic and partly of potential energy.

The ''transfer'' of energy can take various forms; familiar examples include work, heat flow, and advection, as discussed below.

The word "energy" is also used outside of physics in many ways, which can lead to ambiguity and inconsistency. The vernacular terminology is not consistent with technical terminology. For example, while energy is always conserved (in the sense that the total energy does not change despite energy transformations), energy can be converted into a form, e.g., thermal energy, that cannot be utilized to perform work. When one talks about "conserving energy by driving less," one talks about conserving fossil fuels and preventing useful energy from being lost as heat. This usage of "conserve" differs from that of the law of conservation of energy.

In classical physics energy is considered a scalar quantity, the canonical conjugate to time. In special relativity energy is also a scalar (although not a Lorentz scalar but a time component of the energy-momentum 4-vector). In other words, energy is invariant with respect to rotations of space, but not invariant with respect to rotations of space-time (= boosts).

Energy transfer

Because energy is strictly conserved and is also locally conserved (wherever it can be defined), it is important to remember that by the definition of energy the transfer of energy between the "system" and adjacent regions is work. A familiar example is ''mechanical work''. In simple cases this is written as the following equation:

}}

if there are no other energy-transfer processes involved. Here $E$ is the amount of energy transferred, and $W$  represents the work done on the system.

More generally, the energy transfer can be split into two categories:

}}

where $Q$ represents the heat flow into the system.

There are other ways in which an open system can gain or lose energy. In chemical systems, energy can be added to a system by means of adding substances with different chemical potentials, which potentials are then extracted (both of these process are illustrated by fueling an auto, a system which gains in energy thereby, without addition of either work or heat). Winding a clock would be adding energy to a mechanical system. These terms may be added to the above equation, or they can generally be subsumed into a quantity called "energy addition term $E$" which refers to ''any'' type of energy carried over the surface of a control volume or system volume. Examples may be seen above, and many others can be imagined (for example, the kinetic energy of a stream of particles entering a system, or energy from a laser beam adds to system energy, without either being either work-done or heat-added, in the classic senses).

}}

Where E in this general equation represents other additional advected energy terms not covered by work done on a system, or heat added to it.

Energy is also transferred from potential energy ($E\_p$) to kinetic energy ($E\_k$) and then back to potential energy constantly. This is referred to as conservation of energy. In this closed system, energy cannot be created or destroyed; therefore, the initial energy and the final energy will be equal to each other. This can be demonstrated by the following:

}}

The equation can then be simplified further since $E\_p\; =\; mgh$ (mass times acceleration due to gravity times the height) and $E\_k\; =\; \backslash frac\{1\}\{2\}\; mv^2$ (half mass times velocity squared). Then the total amount of energy can be found by adding $E\_p\; +\; E\_k\; =\; E\_\{total\}$.

Energy and the laws of motion

In classical mechanics, energy is a conceptually and mathematically useful property, as it is a conserved quantity. Several formulations of mechanics have been developed using energy as a core concept.

The Hamiltonian

The total energy of a system is sometimes called the Hamiltonian, after William Rowan Hamilton. The classical equations of motion can be written in terms of the Hamiltonian, even for highly complex or abstract systems. These classical equations have remarkably direct analogs in nonrelativistic quantum mechanics.

The Lagrangian

Another energy-related concept is called the Lagrangian, after Joseph Louis Lagrange. This is even more fundamental than the Hamiltonian, and can be used to derive the equations of motion. It was invented in the context of classical mechanics, but is generally useful in modern physics. The Lagrangian is defined as the kinetic energy ''minus'' the potential energy.

Usually, the Lagrange formalism is mathematically more convenient than the Hamiltonian for non-conservative systems (such as systems with friction).

Energy and thermodynamics

Internal energy

Internal energy is the sum of all microscopic forms of energy of a system. It is the energy needed to create the system. It is related to the potential energy, e.g., molecular structure, crystal structure, and other geometric aspects, as well as the motion of the particles, in form of kinetic energy. Thermodynamics is chiefly concerned with changes in internal energy and not its absolute value, which is impossible to determine with thermodynamics alone.

The laws of thermodynamics

According to the second law of thermodynamics, work can be totally converted into heat, but not vice versa. This is a mathematical consequence of statistical mechanics. The first law of thermodynamics simply asserts that energy is conserved, and that heat is included as a form of energy transfer. A commonly used corollary of the first law is that for a "system" subject only to pressure forces and heat transfer (e.g., a cylinder-full of gas), the differential change in energy of the system (with a ''gain'' in energy signified by a positive quantity) is given as the following equation:

:$\backslash mathrm\{d\}E\; =\; T\backslash mathrm\{d\}S\; -\; P\backslash mathrm\{d\}V\backslash ,$,

where the first term on the right is the heat transfer into the system, defined in terms of temperature ''T'' and entropy ''S'' (in which entropy increases and the change d''S'' is positive when the system is heated), and the last term on the right hand side is identified as "work" done on the system, where pressure is ''P'' and volume ''V'' (the negative sign results since compression of the system requires work to be done on it and so the volume change, d''V'', is negative when work is done on the system). Although this equation is the standard textbook example of energy conservation in classical thermodynamics, it is highly specific, ignoring all chemical, electric, nuclear, and gravitational forces, effects such as advection of any form of energy other than heat, and because it contains a term that depends on temperature. The most general statement of the first law (i.e., conservation of energy) is valid even in situations in which temperature is undefinable.

Energy is sometimes expressed as the following equation:

:$\backslash mathrm\{d\}E=\backslash delta\; Q+\backslash delta\; W\backslash ,$,

which is unsatisfactory because there cannot exist any thermodynamic state functions ''W'' or ''Q'' that are meaningful on the right hand side of this equation, except perhaps in trivial cases.

Equipartition of energy

The energy of a mechanical harmonic oscillator (a mass on a spring) is alternatively kinetic and potential. At two points in the oscillation cycle it is entirely kinetic, and alternatively at two other points it is entirely potential. Over the whole cycle, or over many cycles, net energy is thus equally split between kinetic and potential. This is called equipartition principle; total energy of a system with many degrees of freedom is equally split among all available degrees of freedom.

This principle is vitally important to understanding the behavior of a quantity closely related to energy, called entropy. Entropy is a measure of evenness of a distribution of energy between parts of a system. When an isolated system is given more degrees of freedom (i.e., given new available energy states that are the same as existing states), then total energy spreads over all available degrees equally without distinction between "new" and "old" degrees. This mathematical result is called the second law of thermodynamics.

Oscillators, phonons, and photons

In an ensemble (connected collection) of unsynchronized oscillators, the average energy is spread equally between kinetic and potential types.

In a solid, thermal energy (often referred to loosely as heat content) can be accurately described by an ensemble of thermal phonons that act as mechanical oscillators. In this model, thermal energy is equally kinetic and potential.

In an ideal gas, the interaction potential between particles is essentially the delta function which stores no energy: thus, all of the thermal energy is kinetic.

Because an electric oscillator (LC circuit) is analogous to a mechanical oscillator, its energy must be, on average, equally kinetic and potential. It is entirely arbitrary whether the magnetic energy is considered kinetic and whether the electric energy is considered potential, or vice versa. That is, either the inductor is analogous to the mass while the capacitor is analogous to the spring, or vice versa.

1. By extension of the previous line of thought, in free space the electromagnetic field can be considered an ensemble of oscillators, meaning that radiation energy can be considered equally potential and kinetic. This model is useful, for example, when the electromagnetic Lagrangian is of primary interest and is interpreted in terms of potential and kinetic energy.

2. On the other hand, in the key equation $m^2\; c^4\; =\; E^2\; -\; p^2\; c^2$, the contribution $mc^2$ is called the rest energy, and all other contributions to the energy are called kinetic energy. For a particle that has mass, this implies that the kinetic energy is $0.5\; p^2/m$ at speeds much smaller than ''c'', as can be proved by writing $E\; =\; mc^2$ √$(1\; +\; p^2\; m^\{-2\}c^\{-2\})$ and expanding the square root to lowest order. By this line of reasoning, the energy of a photon is entirely kinetic, because the photon is massless and has no rest energy. This expression is useful, for example, when the energy-versus-momentum relationship is of primary interest.

The two analyses are entirely consistent. The electric and magnetic degrees of freedom in item 1 are ''transverse'' to the direction of motion, while the speed in item 2 is ''along'' the direction of motion. For non-relativistic particles these two notions of potential versus kinetic energy are numerically equal, so the ambiguity is harmless, but not so for relativistic particles.

Work and virtual work

Work, a form of energy, is force times distance.

: $W\; =\; \backslash int\_C\; \backslash mathbf\{F\}\; \backslash cdot\; \backslash mathrm\{d\}\; \backslash mathbf\{s\}$

This says that the work ($W$) is equal to the line integral of the force F along a path ''C''; for details see the mechanical work article.

Work and thus energy is frame dependent. For example, consider a ball being hit by a bat. In the center-of-mass reference frame, the bat does no work on the ball. But, in the reference frame of the person swinging the bat, considerable work is done on the ball.

Quantum mechanics

In quantum mechanics energy is defined in terms of the energy operator as a time derivative of the wave function. The Schrödinger equation equates the energy operator to the full energy of a particle or a system. In results can be considered as a definition of measurement of energy in quantum mechanics. The Schrödinger equation describes the space- and time-dependence of slow changing (non-relativistic) wave function of quantum systems. The solution of this equation for bound system is discrete (a set of permitted states, each characterized by an energy level) which results in the concept of quanta. In the solution of the Schrödinger equation for any oscillator (vibrator) and for electromagnetic waves in a vacuum, the resulting energy states are related to the frequency by the Planck equation $E\; =\; h\backslash nu$ (where $h$ is the Planck's constant and $\backslash nu$ the frequency). In the case of electromagnetic wave these energy states are called quanta of light or photons.

Relativity

When calculating kinetic energy (work to accelerate a mass from zero speed to some finite speed) relativistically - using Lorentz transformations instead of Newtonian mechanics, Einstein discovered an unexpected by-product of these calculations to be an energy term which does not vanish at zero speed. He called it rest mass energy - energy which every mass must possess even when being at rest. The amount of energy is directly proportional to the mass of body:

:$E\; =\; m\; c^2$, where :''m'' is the mass, :''c'' is the speed of light in vacuum, :''E'' is the rest mass energy.

For example, consider electron-positron annihilation, in which the rest mass of individual particles is destroyed, but the inertia equivalent of the system of the two particles (its invariant mass) remains (since all energy is associated with mass), and this inertia and invariant mass is carried off by photons which individually are massless, but as a system retain their mass. This is a reversible process - the inverse process is called pair creation - in which the rest mass of particles is created from energy of two (or more) annihilating photons. In this system the matter (electrons and positrons) is destroyed and changed to non-matter energy (the photons). However, the total system mass and energy do not change during this interaction.

In general relativity, the stress-energy tensor serves as the source term for the gravitational field, in rough analogy to the way mass serves as the source term in the non-relativistic Newtonian approximation.

It is not uncommon to hear that energy is "equivalent" to mass. It would be more accurate to state that every energy has an inertia and gravity equivalent, and because mass is a form of energy, then mass too has inertia and gravity associated with it.

Energy and life

Any living organism relies on an external source of energy—radiation from the Sun in the case of green plants; chemical energy in some form in the case of animals—to be able to grow and reproduce. The daily 1500–2000 Calories (6–8 MJ) recommended for a human adult are taken as a combination of oxygen and food molecules, the latter mostly carbohydrates and fats, of which glucose (C₆H₁₂O₆) and stearin (C₅₇H₁₁₀O₆) are convenient examples. The food molecules are oxidised to carbon dioxide and water in the mitochondria ::C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O ::C₅₇H₁₁₀O₆ + 81.5O₂ → 57CO₂ + 55H₂O and some of the energy is used to convert ADP into ATP ::ADP + HPO₄²⁻ → ATP + H₂O The rest of the chemical energy in the carbohydrate or fat is converted into heat: the ATP is used as a sort of "energy currency", and some of the chemical energy it contains when split and reacted with water, is used for other metabolism (at each stage of a metabolic pathway, some chemical energy is converted into heat). Only a tiny fraction of the original chemical energy is used for work: :gain in kinetic energy of a sprinter during a 100 m race: 4 kJ :gain in gravitational potential energy of a 150 kg weight lifted through 2 metres: 3kJ :Daily food intake of a normal adult: 6–8 MJ

It would appear that living organisms are remarkably inefficient (in the physical sense) in their use of the energy they receive (chemical energy or radiation), and it is true that most real machines manage higher efficiencies. In growing organisms the energy that is converted to heat serves a vital purpose, as it allows the organism tissue to be highly ordered with regard to the molecules it is built from. The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings"). Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren. The conversion of a portion of the chemical energy to heat at each step in a metabolic pathway is the physical reason behind the pyramid of biomass observed in ecology: to take just the first step in the food chain, of the estimated 124.7 Pg/a of carbon that is fixed by photosynthesis, 64.3 Pg/a (52%) are used for the metabolism of green plants, i.e. reconverted into carbon dioxide and heat.

Measurement

Because energy is defined as the ability to do work on objects, there is no absolute measure of energy. Only the transition of a system from one state into another can be defined and thus energy is measured in relative terms. The choice of a baseline or zero point is often arbitrary and can be made in whatever way is most convenient for a problem.

Methods

The methods for the measurement of energy often deploy methods for the measurement of still more fundamental concepts of science, namely mass, distance, radiation, temperature, time, electric charge and electric current.

Conventionally the technique most often employed is calorimetry, a thermodynamic technique that relies on the measurement of temperature using a thermometer or of intensity of radiation using a bolometer.

Units

Throughout the history of science, energy has been expressed in several different units such as ergs and calories. At present, the accepted unit of measurement for energy is the SI unit of energy, the joule. In addition to the joule, other units of energy include the kilowatt hour (kWh) and the British thermal unit (Btu). These are both larger units of energy. One kWh is equivalent to exactly 3.6 million joules, and one Btu is equivalent to about 1055 joules.

Energy density

Energy density is a term used for the amount of useful energy stored in a given system or region of space per unit volume.

For fuels, the energy per unit volume is sometimes a useful parameter. In a few applications, comparing, for example, the effectiveness of hydrogen fuel to gasoline it turns out that hydrogen has a higher specific energy than does gasoline, but, even in liquid form, a much lower energy ''density''.

Forms of energy

In the context of physical sciences, several forms of energy have been defined. These include: {| |

Thermal energy, thermal energy in transit is called heat

Chemical energy

Electrical energy

Radiant energy, the energy of electromagnetic radiation

Nuclear energy

|

Magnetic energy

Elastic energy

Sound energy

Mechanical energy

Luminous energy

| |}

These forms of energy may be divided into two main groups; kinetic energy and potential energy. Other familiar types of energy are a varying mix of both potential and kinetic energy.

Energy may be transformed between these forms, some with 100% energy conversion efficiency and others with less. Items that transform between these forms are called transducers.

The above list of the known possible forms of energy is not necessarily complete. Whenever physical scientists discover that a certain phenomenon appears to violate the law of energy conservation, new forms may be added, as is the case with dark energy, a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe.

Classical mechanics distinguishes between potential energy, which is a function of the position of an object, and kinetic energy, which is a function of its movement. Both position and movement are relative to a frame of reference, which must be specified: this is often (and originally) an arbitrary fixed point on the surface of the Earth, the ''terrestrial'' frame of reference. It has been attempted to categorize ''all'' forms of energy as either kinetic or potential: this is not incorrect, but neither is it clear that it is a real simplification, as Feynman points out:

Transformations of energy

One form of energy can often be readily transformed into another with the help of a device- for instance, a battery, from chemical energy to electric energy; a dam: gravitational potential energy to kinetic energy of moving water (and the blades of a turbine) and ultimately to electric energy through an electric generator. Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time. Yet another example is that of a pendulum. At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum. At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy. If one (unrealistically) assumes that there is no friction, the conversion of energy between these processes is perfect, and the pendulum will continue swinging forever.

Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula ''E'' = ''mc''², derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincaré (1900), Friedrich Hasenöhrl (1904) and others (see Mass-energy equivalence#History for further information).

Matter may be destroyed and converted to energy (and vice versa), but mass cannot ever be destroyed; rather, mass remains a constant for both the matter and the energy, during any process when they are converted into each other. However, since $c^2$ is extremely large relative to ordinary human scales, the conversion of ordinary amount of matter (for example, 1 kg) to other forms of energy (such as heat, light, and other radiation) can liberate tremendous amounts of energy (~$9x10^\{16\}$ joules = 21 megatons of TNT), as can be seen in nuclear reactors and nuclear weapons. Conversely, the mass equivalent of a unit of energy is minuscule, which is why a loss of energy (loss of mass) from most systems is difficult to measure by weight, unless the energy loss is very large. Examples of energy transformation into matter (i.e., kinetic energy into particles with rest mass) are found in high-energy nuclear physics.

Transformation of energy into useful work is a core topic of thermodynamics. In nature, transformations of energy can be fundamentally classed into two kinds: those that are thermodynamically reversible, and those that are thermodynamically irreversible. A reversible process in thermodynamics is one in which no energy is dissipated (spread) into empty energy states available in a volume, from which it cannot be recovered into more concentrated forms (fewer quantum states), without degradation of even more energy. A reversible process is one in which this sort of dissipation does not happen. For example, conversion of energy from one type of potential field to another, is reversible, as in the pendulum system described above. In processes where heat is generated, quantum states of lower energy, present as possible excitations in fields between atoms, act as a reservoir for part of the energy, from which it cannot be recovered, in order to be converted with 100% efficiency into other forms of energy. In this case, the energy must partly stay as heat, and cannot be completely recovered as usable energy, except at the price of an increase in some other kind of heat-like increase in disorder in quantum states, in the universe (such as an expansion of matter, or a randomization in a crystal).

As the universe evolves in time, more and more of its energy becomes trapped in irreversible states (i.e., as heat or other kinds of increases in disorder). This has been referred to as the inevitable thermodynamic heat death of the universe. In this heat death the energy of the universe does not change, but the fraction of energy which is available to do produce work through a heat engine, or be transformed to other usable forms of energy (through the use of generators attached to heat engines), grows less and less.

Warren Edward Buffett (; born August 30, 1930) is an American business magnate, investor, and philanthropist. He is widely regarded as one of the most successful investors in the world. Often introduced as "legendary investor, Warren Buffett", he is the primary shareholder, chairman and CEO of Berkshire Hathaway. He is consistently ranked among the world's wealthiest people. He was ranked as the world's wealthiest person in 2008 and is the third wealthiest person in the world as of 2011.

Buffett is called the "Oracle of Omaha" or the "Sage of Omaha" and is noted for his adherence to the value investing philosophy and for his personal frugality despite his immense wealth. Buffett is also a notable philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Gates Foundation. He also serves as a member of the board of trustees at Grinnell College.

Early life

Buffett was born in 1930 in Omaha, Nebraska, the second of three children and only son of U.S. Representative Howard Buffett,, a fierce critic of the interventionist New Deal domestic and foreign policy, and his wife Leila (née Stahl). Buffett began his education at Rose Hill Elementary School in Omaha. In 1942, his father was elected to the first of four terms in the United States Congress, and after moving with his family to Washington, D.C., Warren finished elementary school, attended Alice Deal Junior High School, and graduated from Woodrow Wilson High School in 1947, where his senior yearbook picture reads: "likes math; a future stock broker."

Even as a child, Buffett displayed an interest in making and saving money. He went door to door selling chewing gum, Coca-Cola, or weekly magazines. For a while, he worked in his grandfather's grocery store. While still in high school he was successful in making money by delivering newspapers, selling golfballs and stamps, and detailing cars, among other means. Filing his first income tax return in 1944, Buffett took a $35 deduction for the use of his bicycle and watch on his paper route. In 1945, in his sophomore year of high school, Buffett and a friend spent $25 to purchase a used pinball machine, which they placed in the local barber shop. Within months, they owned several machines in different barber shops.

Buffett's interest in the stock market and investing also dated to his childhood, to the days he spent in the customers' lounge of a regional stock brokerage near the office of his father's own brokerage company. On a trip to New York City at the age of ten, he made a point to visit the New York Stock Exchange. At the age of 11, he bought three shares of Cities Service Preferred for himself, and three for his sister. While in high school he invested in a business owned by his father and bought a farm worked by a tenant farmer. By the time he finished college, Buffett had accumulated more than $90,000 in savings measured in 2009 dollars.

Buffett entered college as a freshmen in 1947 at the Wharton Business School of the University of Pennsylvania and studied there for two years from 1947 to 1949. In the year 1950, when he entered his junior year, he transferred to the University of Nebraska–Lincoln where at the age of nineteen, he graduated with a degree of Bachelor of Science in Business Administration. After the completion of his undergraduate studies, Buffett enrolled at Columbia Business School after learning that Benjamin Graham (author of "The Intelligent Investor" – one of his favorite books on investing) and David Dodd, two well-known securities analysts, taught there. He received a M.S. in Economics from Columbia Business School in 1951. Buffett also attended the New York Institute of Finance. In Buffett’s own words:

The basic ideas of investing are to look at stocks as business, use the market's fluctuations to your advantage, and seek a margin of safety. That’s what Ben Graham taught us. A hundred years from now they will still be the cornerstones of investing.}}

Career

Warren Buffett was employed from 1951–54 at ''Buffett-Falk & Co.'', Omaha as an investment salesman, from 1954–1956 at ''Graham-Newman Corp.'', New York as a securities analyst, from 1956–1969 at ''Buffett Partnership, Ltd.'', Omaha as a general partner and from 1970 – Present at Berkshire Hathaway Inc, Omaha as its Chairman, CEO.

In 1950, at the age of 20, Buffett had made and saved $9,800. In April 1952, Buffett discovered Graham was on the board of GEICO insurance. Taking a train to Washington, D.C. on a Saturday, he knocked on the door of GEICO's headquarters until a janitor allowed him in. There he met Lorimer Davidson, Geico's Vice President, and the two discussed the insurance business for hours. Davidson would eventually become Buffett's life-long friend and a lasting influence and later recall that he found Buffett to be an "extraordinary man" after only fifteen minutes. Buffett graduated from Columbia and wanted to work on Wall Street, however, both his father and Ben Graham urged him not to. He offered to work for Graham for free, but Graham refused.

Buffett returned to Omaha and worked as a stockbroker while taking a Dale Carnegie public speaking course. Using what he learned, he felt confident enough to teach an "Investment Principles" night class at the University of Nebraska-Omaha. The average age of his students was more than twice his own. During this time he also purchased a Sinclair Texaco gas station as a side investment. However, this did not turn out to be a successful business venture.

In 1952 Buffett married Susan Thompson at Dundee Presbyterian Church and the next year they had their first child, Susan Alice Buffett. In 1954, Buffett accepted a job at Benjamin Graham's partnership. His starting salary was $12,000 a year (approximately $97,000 adjusted to 2008 dollars). There he worked closely with Walter Schloss. Graham was a tough man to work for. He was adamant that stocks provide a wide margin of safety after weighting the trade-off between their price and their intrinsic value. The argument made sense to Buffett but he questioned whether the criteria were too stringent and caused the company to miss out on big winners that had more qualitative values. That same year the Buffetts had their second child, Howard Graham Buffett. In 1956, Benjamin Graham retired and closed his partnership. At this time Buffett's personal savings were over $174,000 ($1.2 million inflation adjusted to 2009 dollars) and he started Buffett Partnership Ltd., an investment partnership in Omaha.

In 1957, Buffett had three partnerships operating the entire year. He purchased a five-bedroom stucco house in Omaha, where he still lives, for $31,500. In 1958 the Buffett's third child, Peter Andrew Buffett, was born. Buffett operated five partnerships the entire year. In 1959, the company grew to six partnerships operating the entire year and Buffett was introduced to Charlie Munger. By 1960, Buffett had seven partnerships operating: Buffett Associates, Buffett Fund, Dacee, Emdee, Glenoff, Mo-Buff and Underwood. He asked one of his partners, a doctor, to find ten other doctors willing to invest $10,000 each in his partnership. Eventually eleven agreed, and Buffett pooled their money with a mere $100 original investment of his own. In 1961, Buffett revealed that Sanborn Map Company accounted for 35% of the partnership's assets. He explained that in 1958 Sanborn stock sold at only $45 per share when the value of the Sanborn investment portfolio was $65 per share. This meant that buyers valued Sanborn stock at "minus $20" per share and were unwilling to pay more than 70 cents on the dollar for an investment portfolio with a map business thrown in for nothing. This earned him a spot on the board of Sanborn.

As a millionaire

In 1962, Buffett became a millionaire because of his partnerships, which in January 1962 had an excess of $7,178,500, of which over $1,025,000 belonged to Buffett. Buffett merged all partnerships into one partnership. Buffett invested in and eventually took control of a textile manufacturing firm, Berkshire Hathaway. Buffett's partnerships began purchasing shares at $7.60 per share. In 1965, when Buffett's partnerships began purchasing Berkshire aggressively, they paid $14.86 per share while the company had working capital of $19 per share. This did not include the value of fixed assets (factory and equipment). Buffett took control of Berkshire Hathaway at the board meeting and named a new president, Ken Chace, to run the company. In 1966, Buffett closed the partnership to new money. Buffett wrote in his letter: "... unless it appears that circumstances have changed (under some conditions added capital would improve results) or unless new partners can bring some asset to the partnership other than simply capital, I intend to admit no additional partners to BPL."

In a second letter, Buffett announced his first investment in a private business — Hochschild, Kohn and Co, a privately owned Baltimore department store. In 1967, Berkshire paid out its first and only dividend of 10 cents. In 1969, following his most successful year, Buffett liquidated the partnership and transferred their assets to his partners. Among the assets paid out were shares of Berkshire Hathaway. In 1970, as chairman of Berkshire Hathaway, Buffett began writing his now-famous annual letters to shareholders. However, he lived solely on his salary of $50,000 per year, and his outside investment income. In 1979, Berkshire began the year trading at $775 per share, and ended at $1,310. Buffett's net worth reached $620 million, placing him on the Forbes 400 for the first time.

In 1973, Berkshire began to acquire stock in the Washington Post Company. Buffett became close friends with Katharine Graham, who controlled the company and its flagship newspaper, and became a member of its board of directors. In 1974, the SEC opened a formal investigation into Warren Buffett and Berkshire's acquisition of WESCO, due to possible conflict of interest. No charges were brought. In 1977, Berkshire indirectly purchased the ''Buffalo Evening News'' for $32.5 million. Antitrust charges started, instigated by its rival, the ''Buffalo Courier-Express''. Both papers lost money, until the ''Courier-Express'' folded in 1982.

In 1979, Berkshire began to acquire stock in ABC. Capital Cities announced $3.5 billion purchase of ABC on March 18, 1985 surprised the media industry, as ABC was four times bigger than Capital Cities at the time. Berkshire Hathaway chairman Warren Buffett helped finance the deal in return for a 25% stake in the combined company. The newly merged company, known as Capital Cities/ABC (or CapCities/ABC), was forced to sell off some stations due to FCC ownership rules. Also, the two companies owned several radio stations in the same markets.

In 1987, Berkshire Hathaway purchased a 12% stake in Salomon Inc., making it the largest shareholder and Buffett the director. In 1990, a scandal involving John Gutfreund (former CEO of Salomon Brothers) surfaced. A rogue trader, Paul Mozer, was submitting bids in excess of what was allowed by the Treasury rules. When this was discovered and brought to the attention of Gutfreund, he did not immediately suspend the rogue trader. Gutfreund left the company in August 1991. Buffett became Chairman of Salomon until the crisis passed; on September 4, 1991, he testified before Congress. In 1988, Buffett began buying stock in Coca-Cola Company, eventually purchasing up to 7% of the company for $1.02 billion. It would turn out to be one of Berkshire's most lucrative investments, and one which it still holds.

As a billionaire

Buffett became a billionaire on paper when Berkshire Hathaway began selling class A shares on May 29, 1990, when the market closed at $7,175 a share. In 1998, in an unusual move, he acquired General Re (Gen Re) for stock. In 2002, Buffett became involved with Maurice R. Greenberg at AIG, with General Re providing reinsurance. On March 15, 2005, AIG's board forced Greenberg to resign from his post as Chairman and CEO under the shadow of criticism from Eliot Spitzer, former attorney general of the state of New York. On February 9, 2006, AIG and the New York State Attorney General's office agreed to a settlement in which AIG would pay a fine of $1.6 billion. In 2010, the federal government settled with Berkshire Hathaway for $92 million in return for the firm avoiding prosecution in an AIG fraud scheme, and undergoing 'corporate governance concessions'.

In 2002, Buffett entered in $11 billion worth of forward contracts to deliver U.S. dollars against other currencies. By April 2006, his total gain on these contracts was over $2 billion. In 2006, Buffett announced in June that he gradually would give away 85% of his Berkshire holdings to five foundations in annual gifts of stock, starting in July 2006. The largest contribution would go to the Bill and Melinda Gates Foundation. In 2007, in a letter to shareholders, Buffett announced that he was looking for a younger successor, or perhaps successors, to run his investment business. Buffett had previously selected Lou Simpson, who runs investments at Geico, to fill that role. However, Simpson is only six years younger than Buffett.

Late 2000s recession

Buffett ran into criticism during the subprime crisis of 2007–2008, part of the late 2000s recession, that he had allocated capital too early resulting in suboptimal deals. “Buy American. I am.” he wrote for an opinion piece published recently in the New York Times. Buffett has called the 2007—present downturn in the financial sector "poetic justice". Buffett's Berkshire Hathaway suffered a 77% drop in earnings during Q3 2008 and several of his recent deals appear to be running into large mark-to-market losses.

Berkshire Hathaway acquired 10% perpetual preferred stock of Goldman Sachs. Some of Buffett's Index put options (European exercise at expiry only) that he wrote (sold) are currently running around $6.73 billion mark-to-market losses. The scale of the potential loss prompted the SEC to demand that Berkshire produce, "a more robust disclosure" of factors used to value the contracts. Buffett also helped Dow Chemical pay for its $18.8 billion takeover of Rohm & Haas. He thus became the single largest shareholder in the enlarged group with his Berkshire Hathaway, which provided $3 billion, underlining his instrumental role during the current crisis in debt and equity markets.

In 2008, Buffett became the richest man in the world dethroning Bill Gates, worth $62 billion according to Forbes, and $58 billion according to Yahoo. Bill Gates had been number one on the Forbes list for 13 consecutive years. In 2009, Bill Gates regained number one of the list according to Forbes magazine, with Buffett second. Their values have dropped to $40 billion and $37 billion respectively, Buffett having (according to Forbes) lost $25 billion in 12 months during 2008/2009.

In October 2008, the media reported that Warren Buffett had agreed to buy General Electric (GE) preferred stock. The operation included extra special incentives: he received an option to buy 3 billion GE at $22.25 in the next five years, and also received a 10% dividend (callable within three years). In February 2009, Buffett sold some of the Procter & Gamble Co, and Johnson & Johnson shares from his portfolio.

In addition to suggestions of mistiming, questions have been raised as to the wisdom in keeping some of Berkshire's major holdings, including The Coca-Cola Company (NYSE:KO) which in 1998 peaked at $86. Buffett discussed the difficulties of knowing when to sell in the company's 2004 annual report:

That may seem easy to do when one looks through an always-clean, rear-view mirror. Unfortunately, however, it’s the windshield through which investors must peer, and that glass is invariably fogged.

In March 2009, Buffett stated in a cable television interview that the economy had "fallen off a cliff... Not only has the economy slowed down a lot, but people have really changed their habits like I haven't seen". Additionally, Buffett fears we may revisit a 1970s level of inflation, which led to a painful stagflation that lasted many years.

In 2009, Warren Buffett invested $2.6 billion as a part of Swiss Re's raising equity capital. Berkshire Hathaway already owns a 3% stake, with rights to own more than 20%. In 2009, Warren Buffett acquired Burlington Northern Santa Fe Corp. for $34 billion in cash and stock. Alice Schroeder, author of Snowball, stated that a reason for the purchase was to diversify Berkshire Hathaway from the financial industry. Measured by market capitalization in the Financial Times Global 500 Berkshire Hathaway as of June 2009 was the eighteenth largest corporation on earth.

In 2009, Buffett divested his failed investment in ConocoPhillips, saying to his Berkshire investors,

I bought a large amount of ConocoPhillips stock when oil and gas prices were near their peak. I in no way anticipated the dramatic fall in energy prices that occurred in the last half of the year. I still believe the odds are good that oil sells far higher in the future than the current $40–$50 price. But so far I have been dead wrong. Even if prices should rise, moreover, the terrible timing of my purchase has cost Berkshire several billion dollars.

The merger with the Burlington Northern Santa Fe Railway (BNSF) closed upon BNSF shareholder approval in 1Q2010. This deal is valued at approximately $34 billion and reflects an increase of a previously existing stake of about 22%.

In June 2010, Buffett defended the credit rating agencies for their role in the US financial crisis, claiming that:

Very, very few people could appreciate the bubble. That's the nature of bubbles – they're mass delusions.

On March 18, 2011, Goldman Sachs acquired Federal Reserve approval to buy back Berkshire's preferred stock in Goldman. Buffet has been reluctant to give up the stock which averages $1.4 million in dividend a day, stating:

I'm going to be the Osama bin Laden of capitalism. I'm on my way to an unknown destination in Asia where I'm going to look for a cave. If the U.S. Armed forces can't find Osama bin Laden in 10 years, let Goldman Sachs try to find me.

Personal life

Buffett married Susan Buffett (née Thompson) in 1952. They had three children, Susie, Howard and Peter. The couple began living separately in 1977, although they remained married until her death in July 2004. Their daughter, Susie, lives in Omaha and does charitable work through the Susan A. Buffett Foundation and is a national board member of Girls, Inc. In 2006, on his seventy-sixth birthday, Warren married his never-married longtime-companion, Astrid Menks, who was then 60 years old. She had lived with him since his wife's departure to San Francisco in 1977. It was Susan Buffett who arranged for the two to meet before she left Omaha to pursue her singing career. All three were close and Christmas cards to friends were signed "Warren, Susie and Astrid". Susan Buffett briefly discussed this relationship in an interview on the Charlie Rose Show shortly before her death, in a rare glimpse into Buffett's personal life.

Warren Buffett disowned his son Peter's adopted daughter, Nicole, in 2006 after she participated in the Jamie Johnson documentary, ''The One Percent.'' Although his first wife had referred to Nicole as one of her "adored grandchildren", Buffett wrote her a letter stating, "I have not emotionally or legally adopted you as a grandchild, nor have the rest of my family adopted you as a niece or a cousin." He signed the letter "Warren."

His 2006 annual salary was about $100,000, which is small compared to senior executive remuneration in comparable companies. In 2007 and 2008, he earned a total compensation of $175,000, which included a base salary of just $100,000. He lives in the same house in the central Dundee neighborhood of Omaha that he bought in 1958 for $31,500, today valued at around $700,000 (although he also owns a $4 million house in Laguna Beach, California). In 1989 after having spent nearly 6.7 million dollars of Berkshire's funds on a private jet, Buffett sheepishly named it "''The Indefensible''". This act was a break from his past condemnation of extravagant purchases by other CEOs and his history of using more public transportation.

He remains an avid player of bridge, which he learned from Sharon Osberg, and plays with her and Bill Gates. He spends twelve hours a week playing the game. In 2006, he sponsored a bridge match for the Buffett Cup. Modeled on the Ryder Cup in golf, held immediately before it, and in the same city, a team of twelve bridge players from the United States took on twelve Europeans in the event. He is a dedicated, lifelong follower of Nebraska football, and attends as many games as his schedule permits. He supported the hire of Bo Pelini following the 2007 season stating, "It was getting kind of desperate around here". He watched the 2009 game against Oklahoma from the Nebraska sideline after being named an honorary assistant coach.

Warren Buffett worked with Christopher Webber on an animated series with chief Andy Heyward, of DiC Entertainment, and then A Squared Entertainment. The series features Buffett and Munger, and teaches children healthy financial habits for life. Buffett was raised Presbyterian but has since described himself as agnostic. In December 2006 it was reported that Buffett does not carry a cell phone, does not have a computer at his desk, and drives his own automobile, a Cadillac DTS. Buffett wears tailor-made suits from the Chinese label Trands; earlier he wore Ermenegildo Zegna.

Lineage

Buffett's DNA report revealed that his paternal ancestors hail from northern Scandinavia, while his maternal ancestors most likely have roots in Iberia or Estonia.

Recognition

In 1999, Buffett was named the top money manager of the Twentieth Century in a survey by the Carson Group, ahead of Peter Lynch and John Templeton. In 2007, he was listed among ''Time'''s 100 Most Influential People in the world. In 2011, President Barack Obama awarded him the Presidential Medal of Freedom. Most recently, Buffett, along with Bill Gates, was named the most influential global thinker in Foreign Policy's 2010 report.

Politics

In addition to other political contributions over the years, Buffett has formally endorsed and made campaign contributions to Barack Obama's presidential campaign. On July 2, 2008, Buffett attended a $28,500 per plate fundraiser for Obama's campaign in Chicago hosted by Obama's National Finance Chair, Penny Pritzker and her husband, as well as Obama advisor Valerie Jarrett. Buffett backed Obama for president, and intimated that John McCain's views on social justice were so far from his own that McCain would need a "lobotomy" for Buffett to change his endorsement. During the second 2008 U.S. presidential debate, candidates John McCain and Barack Obama, after being asked first by presidential debate mediator Tom Brokaw, both mentioned Buffett as a possible future Secretary of the Treasury. Later, in the third and final presidential debate, Obama mentioned Buffett as a potential economic advisor. Buffett was also finance advisor to California Republican Governor Arnold Schwarzenegger during his 2003 election campaign.

Writings

Warren Buffett's writings include his annual reports and various articles. Buffett is recognized by communicators as a great story-teller, as evidenced by his annual letters to shareholders. He warned about the pernicious effects of inflation:

In his article ''The Superinvestors of Graham-and-Doddsville'', Buffett rebutted the academic Efficient-market hypothesis, that beating the S&P 500 was "pure chance", by highlighting the results achieved by a number of students of the Graham and Dodd value investing school of thought. In addition to himself, Buffett named Walter J. Schloss, Tom Knapp, Ed Anderson (Tweedy, Brown Inc.), Bill Ruane (Sequoia Fund, Inc.), Charles Munger (Buffett's own business partner at Berkshire), Rick Guerin (Pacific Partners, Ltd.), and Stan Perlmeter (Perlmeter Investments). In his November 1999 ''Fortune'' article, he warned of investors' unrealistic expectations:

Wealth

In 2008 he was ranked by ''Forbes'' as the richest person in the world with an estimated net worth of approximately US$62 billion. In 2009, after donating billions of dollars to charity, Buffett was ranked as the second richest man in the United States with a net worth of US$37 billion with only Bill Gates ranked higher than Buffett. His net worth is up to $47 billion in the past 12 months.

Philanthropy

The following quotation from 1988 highlights Warren Buffett's thoughts on his wealth and why he long planned to re-allocate it:

From a ''NY Times'' article: "I don't believe in dynastic wealth", Warren Buffett said, calling those who grow up in wealthy circumstances "members of the lucky sperm club". Buffett has written several times of his belief that, in a market economy, the rich earn outsized rewards for their talents:

His children will not inherit a significant proportion of his wealth. This is consistent with statements he has made in the past indicating his opposition to the transfer of great fortunes from one generation to the next. Buffett once commented, "I want to give my kids just enough so that they would feel that they could do anything, but not so much that they would feel like doing nothing".

In June 2006, he announced a plan to give away his fortune to charity, with 83% of it going to the Bill & Melinda Gates Foundation. He pledged about the equivalent of 10 million Berkshire Hathaway Class B shares to the Bill & Melinda Gates Foundation (worth approximately US$30.7 billion as of June 23, 2006), making it the largest charitable donation in history, and Buffett one of the leaders of philanthrocapitalism. The foundation will receive 5% of the total donation on an annualised basis each July, beginning in 2006. (Significantly, however, the pledge is conditional upon the foundation's giving away each year, beginning in 2009, an amount that is at least equal to the value of the entire previous year's gift from Buffett, in addition to 5% of the foundation's net assets.) Buffett also will join the board of directors of the Gates Foundation, although he does not plan to be actively involved in the foundation's investments.

This is a significant shift from previous statements Buffett has made, having stated that most of his fortune would pass to his Buffett Foundation. The bulk of the estate of his wife, valued at $2.6 billion, went to that foundation when she died in 2004. He also pledged $50-million to the Nuclear Threat Initiative, in Washington, where he has served as an adviser since 2002.

In 2006, he auctioned his 2001 Lincoln Town Car on eBay to raise money for Girls, Inc. In 2007, he auctioned a luncheon with himself that raised a final bid of $650,100 for a charity. On June 27, 2008, Zhao Danyang, a general manager at Pure Heart China Growth Investment Fund, won the 2008 5-day online "Power Lunch with Warren Buffett" charity auction with a bid of $2,110,100. Auction proceeds benefit the San Francisco Glide Foundation. The following year, executives from Toronto-based Salida Capital paid US$1.68 million to dine with Buffett.

In a letter to Fortune Magazine's website in 2010 Buffett remarked:

This statement was made as part of a joint proposal with Bill Gates to encourage other wealthy individuals to pool some of their fortunes for charitable purposes.

Bill Gates's wife Melinda urged people to learn a lesson from the philanthropic efforts of the family that sold its home and gave away half of its value, as detailed in ''The Power of Half''. On December 9, 2010, Buffett, Bill Gates, and Mark Zuckerberg (Facebook's CEO), signed a promise they called the "Gates-Buffett Giving Pledge", in which they promised to donate to charity at least half of their wealth over time, and invited others among the wealthy to donate 50% or more of their wealth to charity.

Public positions

Buffett's speeches are known for mixing business discussions with humor. Each year, Buffett presides over Berkshire Hathaway's annual shareholder meeting in the Qwest Center in Omaha, Nebraska, an event drawing over 20,000 visitors from both United States and abroad, giving it the nickname "Woodstock of Capitalism". Berkshire's annual reports and letters to shareholders, prepared by Buffett, frequently receive coverage by the financial media. Buffett's writings are known for containing quotations from sources as ranging between the Bible and Mae West, as well as advice in a Midwestern folk style, and numerous jokes.

Tobacco

During the RJR Nabisco, Inc. hostile takeover fight in 1987, Buffett was quoted as telling John Gutfreund:

Speaking at Berkshire Hathaway Inc.'s 1994 annual meeting, Buffett said investments in tobacco are:

Coal

In 2007, Buffett's PacifiCorp, a subsidiary of his MidAmerican Energy Company, canceled six proposed coal-fired power plants. These included Utah's Intermountain Power Project Unit 3, Jim Bridger Unit 5, and four proposed plants previously included in PacifiCorp's Integrated Resource Plan. The cancellations came in the wake of pressure from regulators and citizen groups, including a petition drive organized by Salt Lake City commercial real estate broker Alexander Lofft and directed at Buffett personally. The 1,600 petitioners, who described themselves in a letter to Buffett as "a collection of citizens, business owners and managers, service professionals, public servants, and organization representatives ... your friends and new customers here in Utah," explained that, in their view, any further expansion of coal generation in Utah would "compromise our health, obscure our viewsheds, shrink and contaminate our watersheds, and thin out our most beloved snow pack," concluding that "our attractiveness as a place to live and work is also threatened, and so is our economic competitiveness as a major metro area and a state, compromising our recent gains in income and property values".

Klamath river

American Indian tribes and salmon fishermen sought to win support from Warren Buffett for a proposal to remove four hydroelectric dams from the Klamath River. He had David Sokol respond that the FERC would decide the question.

Trade deficit

Buffett views the United States' expanding trade deficit as a trend that will devalue the US dollar and US assets. He believes that the US dollar will lose value in the long run, as a result of putting a larger portion of ownership of US assets in the hands of foreigners. In his letter to shareholders in March 2005, Warren Buffett predicted that in another ten years’ time the net ownership of the U.S. by outsiders would amount to $11 trillion.

Americans ... would chafe at the idea of perpetually paying tribute to their creditors and owners abroad. A country that is now aspiring to an ‘ownership society’ will not find happiness in – and I’ll use hyperbole here for emphasis – a 'sharecropping society’.

Author Ann Pettifor has adopted the image in her writings and has stated: "He is right. And so the thing we must fear most now, is not just the collapse of banks and investment funds, or of the international financial architecture, but of a 'sharecropper society, angry at its downfall".

Dollar and gold

The trade deficit induced Buffett to enter the foreign currency market for the first time in 2002. However, he substantially reduced his stake in 2005 as changing interest rates increased the costs of holding currency contracts. Buffett continues to be bearish on the dollar, and says he is looking to acquire companies which derive a substantial portion of their revenues from outside the United States. Buffett emphasized the non-productive aspect of a gold standard for the USD in 1998 at Harvard:

It gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head.

In 1977 Buffett was also quoted as saying about stocks, gold, farmland, and inflation:

Stocks are probably still the best of all the poor alternatives in an era of inflation – at least they are if you buy in at appropriate prices.

Taxes

Buffett stated that he only paid 19% of his income for 2006 ($48.1 million) in total federal taxes (due to their being from dividends & capital gains), while his employees paid 33% of theirs, despite making much less money. “How can this be fair?” Buffet asked, regarding how little he pays in taxes compared to his employees. “How can this be right?” He also added:

: “There’s class warfare, all right, but it’s my class, the rich class, that’s making war, and we’re winning.”

Buffett favors the inheritance tax, saying that repealing it would be like "choosing the 2020 Olympic team by picking the eldest sons of the gold-medal winners in the 2000 Olympics". In 2007, Buffett testified before the Senate and urged them to preserve the estate tax so as to avoid a plutocracy. Some critics have argued that Buffett (through Berkshire Hathaway) has a personal interest in the continuation of the estate tax, since Berkshire Hathaway has benefited from the estate tax in past business dealings and had developed and marketed insurance policies to protect policy holders against future estate tax payments. Buffett believes government should not be in the business of gambling, or legalizing casinos, calling it a tax on ignorance.

Expensing of stock options

He has been a strong proponent of stock option expensing on the Income Statement. At the 2004 annual meeting, he lambasted a bill before the United States Congress that would consider only some company-issued stock options compensation as an expense, likening the bill to one that was almost passed by the Indiana House of Representatives to change the value of Pi from 3.14159 to 3.2 through legislative fiat.

When a company gives something of value to its employees in return for their services, it is clearly a compensation expense. And if expenses don't belong in the earnings statement, where in the world do they belong?

Investing in China

Buffett invested in PetroChina Company Limited and in a rare move, posted a commentary on Berkshire Hathaway's website stating why he would not divest from the company despite calls from some activists to do so, due to its connection with the Sudanese civil war that caused Harvard to divest from the company in 2005. He did, however, sell this stake soon afterwards, sparing him the billions of dollars he would have lost had he held on to the company in the midst of the steep drop in oil prices beginning in the summer of 2008.

In October 2008, Buffett invested in new energy automobile business by paying $230 million for 10% of BYD Company (), which runs a subsidiary of electric automobile manufacturer BYD Auto. In less than one year, the investment has reaped him over 500% return of profit.

Books about Buffett

Numerous books have been written about Warren Buffett and his investment strategies. In October 2008, ''USA Today'' reported that there were at least 47 books in print with Buffett's name in the title. The article quoted the CEO of Borders Books, George Jones, as saying that the only other living persons named in as many book titles were U.S. presidents, major world political figures, and the Dalai Lama. Buffett said that his own personal favorite is a collection of his essays called ''The Essays of Warren Buffett'', which he described as "a coherent rearrangement of ideas from my annual report letters" as edited by Larry Cunningham.

Vinod Khosla (विनोद खोसला (Devanagari), ਵਿਨੋਦ ਖੋਸਲਾ (Gurmukhi); born 28 January 1955) is an Indian-born American venture capitalist and an influential personality in Silicon Valley.

Khosla was one of the co-founders of Sun Microsystems, where he would serve as its first CEO & Chairman in the early 1980s. In 1986, he became a general partner of the venture capital firm Kleiner Perkins Caufield & Byers, where he would remain through the early 2000s.

In 2004 Khosla formed his own firm, Khosla Ventures, which focused on venture investments in various technology sectors, most notably clean technology.

He is also known for his witty but controversial statements, for example: "If it doesn't scale, it doesn't matter. Most of what we talk about today—hybrid, biodiesel, ethanol, solar photovoltaics, geothermal—I believe are irrelevant to the scale of the problem."

Early life and education

Khosla's father was in the army and was posted at New Delhi, India. He read about the founding of Intel in ''Electronic Engineering Times'' at the age of fourteen and this inspired him to pursue technology as a career.

Khosla went on to receive degrees from the IIT Delhi, India (Bachelor of Technology in Electrical Engineering ), Carnegie Mellon University (Masters in Biomedical Engineering), and Stanford Graduate School of Business (MBA).

Career

After graduating from Stanford University in 1980, Khosla worked for electronic design automation company Daisy Systems. Then in 1982, Khosla co-founded Sun Microsystems (SUN is the acronym for the Stanford University Network), along with his Stanford classmates Scott McNealy, Andy Bechtolsheim, and UC Berkeley computer science graduate student Bill Joy. Khosla served as the first Chairman and CEO of Sun Microsystems from 1982 to 1984, when he left the company to become a venture capitalist.

In 1986, Khosla joined the venture capital firm Kleiner Perkins Caufield & Byers as a general partner. At Kleiner, Khosla became a recognized venture capitalist, with several successful early stage investments. Khosla also played a key role with several of the tech industry's most spectacular failures, including Asera, Dynabook, and others.

He also invested in an Indian Microfinance NGO, SKS Microfinance, which lends small loans to poor women in rural India. Khosla is also one of the founders of TiE, The Indus Entrepreneurs, and has guest-edited a special issue of The Economic Times(ET), a leading business newspaper in India.

Khosla was featured on Dateline NBC in May 2006 where he discussed the practicality of ethanol as a gasoline substitute. He is known to have invested heavily in ethanol companies, in hopes of widespread adoption. He cites Brazil as an example of a country that has ended its dependence on foreign oil.

Khosla was a major proponent of the "Yes on 87" campaign to pass California's Proposition 87, The Clean Energy Initiative, which failed to pass in November, 2006. In 2006, Khosla's wife Neeru co-founded the CK-12 Foundation that aims to develop open source textbooks and lower the cost of education in America and the rest of the world. Khosla and his wife are also donors to the Wikimedia Foundation, in the amount of $500,000.

Khosla Ventures

In 2004 Khosla formed his own venture capital firm, Khosla Ventures. The firm is based in Menlo Park, California and manages approximately $1 billion of investor capital as well as investments funded by Khosla himself.

In September 2009, Khosla completed fundraising for two new funds, to invest in cleantech and information technology start-ups. Khosla Ventures III secured $750 million of investor commitments to invest in traditional early stage and growth stage companies. Khosla also raised $250 million for Khosla Seed, which will invest in higher-risk opportunities.

In May 2010 it was announced that former British Prime Minister Tony Blair was to join Khosla Ventures to provide strategic advice regarding investments in technologies focused on the environment.

Other accomplishments and affiliations

In addition to his role in founding Sun Microsystems, Khosla has been involved in the founding of a number of other businesses and organizations. Khosla was also involved with the founding of Daisy Systems in 1981. He is also one of the founders of TiE, The Indus Entrepreneurs, and has guest-edited a special issue of Economic Times (ET), a leading business newspaper in India.

Khosla was a finalist for the 1999 World Technology Award and served as the Honorary Chair of the DonorsChoose San Francisco Bay Area Advisory Board. In addition, Khosla is a Member of the Board of Trustees of the Blum Center for Developing Economies at the University of California, Berkeley. The Center is focused on finding solutions to address the crisis of extreme poverty and disease in the developing world.

Tulsi Tanti is the chairman and managing director of Suzlon Energy, a US $2 billion market cap wind power based company. He, along with his three siblings, own 58% of the company. He is from Rajkot Gujarat where he started his first venture which was in textiles in Surat called Sulzer Synthetics P. Ltd. later changed name Suzlon Synthetics Ltd. And there after Suzlon Fibres Ltd,, then he moved into wind energy production and founded Suzlon Energy. He was worth $930 million as per Forbes in November 2008. However an 85% drop in share price of his Suzlon Energy, precipitated by the global recession and reliability issues with Suzlon's wind turbine blades, caused his net worth to drop to $400 million.

A commerce graduate and a diploma holder in mechanical engineering, Tulsi Tanti originally hails from Rajkot City Of Gujarat and is presently based in Pune, Maharashtra. Tulsi Tanti was earlier into textiles. He started his textile business with name of Sulzer Synthetics P. Ltd. in Surat, Gujarat. But he found the prospects stunted due to infrastructural bottlenecks. The biggest of them all was the cost and unavailability of power, which formed a high proportion of operating expenses of textile industry.

In 1990, Tulsi Tanti invested in two Vestas wind turbines and realized their huge potential. In 1995, he formed Suzlon and gradually quit textiles. Suzlon Energy is the third largest wind turbine manufacturer in the world and the largest in Asia. It is presently building what will be among the world's largest wind parks of its kind at 1,000 MW capacity.

Suzlon is currently concentrating on a global expansion drive. It recently acquired Hansen Transmissions, a Belgian maker of wind-turbine gearboxes. Suzlon is also building a rotor-blade factory in Minnesota and has invested $60m in a factory in Tianjin, China.

Kisan Baburao Hazare () (born 15 June 1937), popularly known as Anna Hazare () is an Indian social activist and a prominent leader in the 2011 Indian anti-corruption movement, using nonviolent methods following the teachings of Mahatma Gandhi. Hazare also contributed to the development and structuring of Ralegan Siddhi, a village in Parner taluka of Ahmednagar district, Maharashtra, India. He was awarded the Padma Bhushan—the third-highest civilian award—by the Government of India in 1992 for his efforts in establishing this village as a model for others.

Anna Hazare started an indefinite hunger strike on 5 April 2011 to exert pressure on the Indian government to enact a stringent anti-corruption law as envisaged in the Jan Lokpal Bill, for the institution of an ombudsman with the power to deal with corruption in public places. The fast led to nation-wide protests in support of Hazare. The fast ended on 9 April 2011, a day after the government accepted Hazare's demands. The government issued a gazette notification on the formation of a joint committee, consisting of government and civil society representatives, to draft the legislation.

For the year 2011 Foreign Policy magazine has named him among top 100 global thinkers. Anna has been ranked as the most influential person in Mumbai by a national daily newspaper. He has faced criticism for his authoritarian views on justice, including death as punishment for corrupt public officials and his alleged support for forced vasectomies as a method of family planning.

Early life

Kisan Hazare was born on 15 June 1937 (some sources say 1940) in Bhingar, near to Ahmednagar. The eldest son, with two sisters and four brothers, the later adoption of the name ''Anna'' reflects the Indian word for "elder brother". His father worked in a pharmacy and struggled to support the family financially. In time, the family moved to their ancestral village of Ralegan Siddhi, where they owned a small amount of agricultural land. A relative took on the burden of providing Kisan with an education, taking him to Mumbai because the village had no primary school. The relative became unable financially to continue the support and Kisan's schooling ended in the Standard Seventh grade; his siblings were not schooled at all. He started selling flowers at the Dadar railway station in Mumbai and was able eventually to own two flower shops in the city. He also became involved in vigilantism, joining groups who acted to prevent the poor from being bullied out of their shelters by thugs in the employ of landlords.

Military service

The Indo-China War of 1962 caused the Indian Army to commence emergency recruitment measures. Hazare was recruited in April 1963, despite not meeting the physical requirements, and was attested as a soldier on 16 November of that year after undertaking training at Aurangabad.

During the Indo-Pakistani War of 1965, Hazare was posted at the border in the Khem Karan sector. He was the sole survivor of an enemy attack - variously claimed to have been a bomb, an aerial assault and an exchange of fire at the border - while he was driving a truck. The experiences of war time, coupled with the poverty from which he had come, affected him. He had considered suicide at one point but now turned to pondering the meaning of life and death. He has said of the truck attack that "[It] sent me thinking. I felt that God wanted me to stay alive for some reason. I was re-born in the battlefield of Khem Karan. And I decided to dedicate my new life to serving people." He spent his spare time reading the works of Swami Vivekananda, Gandhi, and Vinoba Bhave. In a blog post, Hazare expressed his views on Kashmir by saying that it was his "active conviction that Kashmir is an integral part of India" and that if required once again for service, he would remain "ready to take part in war against Pakistan."

During the mid-1970s, Hazare survived a road accident while driving for the army. He interpreted his survival as a further sign that his life was intended to be dedicated to the service of the community. Despite subsequent allegations that he had deserted from the army, official records show that he was honourably discharged in 1975 after completing his 12 years of service.

Transformation of Ralegan Siddhi

Hazare returned to Ralegan Siddhi, a village described by Satpathy and Mehta as being then "one of the many villages of India plagued by acute poverty, deprivation, a fragile ecosystem, neglect and hopelessness."

Although most of the villagers owned some land, cultivation was extremely difficult due to the rocky ground preventing retention of the monsoon rains; this situation had not been assisted by a gradual deterioration as trees were cut down, erosion spread and droughts were also experienced. The shortage of water also led to disease because conditions became unsanitary and water was re-used for multiple purposes. The economy of the village had become reliant on illegal manufacture and sale of alcohol, a product to which many of the villagers had themselves become addicted. Many inhabitants were at the mercy of moneylenders in order to survive, and those lenders would charge monthly interest rates of as much as 10%. Crime and violence (including domestic violence) had become commonplace, while education and employment opportunities were poor.

Hazare was relatively wealthy because of the gratuity from his army service. He set about using that money to restore a run-down, vandalised village temple as a focal point for the community. Some were able to respond with small financial donations but many other villagers, particularly among the elderly, donated their labour in a process that became known as ''shramdaan''. Some youths also became involved in the work and these he organised into a ''Tarun Mandal'' (Youth Association). One of the works of Vivekananda which he had read was ''Call to the youth for nation building''.

Prohibition of alcohol

Hazare and the youth group decided to take up the issue of alcoholism as a means to drive a process of reform. At a meeting conducted in the temple, the villagers resolved to close down liquor dens and ban alcohol in the village. Since these resolutions were made in the temple, they became, in a sense, religious commitments. Over thirty liquor brewing units were closed by their owners voluntarily. Those who did not succumb to social pressure were forced to close down their businesses when the youth group smashed up their liquor dens. The owners could not complain as their businesses were illegal.

When some villagers were found to be drunk they were tied to pillars and then flogged, sometimes personally by Hazare. He justified this punishment by stating that “rural India was a harsh society”, and that }}

Hazare appealed to the government of Maharashtra to bring in a law whereby prohibition would come into force in a village if 25% of the women in the village demanded it. In 2009 the state government amended the Bombay Prohibition Act, 1949 to reflect this.

Grain Bank

In 1980, the Grain Bank was started by him at the temple, with the objective of providing food security to needful farmers during times of drought or crop failure. Rich farmers, or those with surplus grain production, could donate a quintal to the bank. In times of need, farmers could borrow the grain, but they had to return the same amount of grain they borrowed, plus an additional quintal as an interest. This ensured that nobody in the village ever went hungry or had to borrow money to buy grain. This also prevented distress sales of grain at lower prices at harvest time.

Watershed development programme

Ralegan is located in the foothills, so Hazare persuaded villagers to construct a watershed embankment and associated works to stop water and allow it to percolate and increase the ground water level and improve irrigation in the area. These efforts solved the problem of water scarcity in the village and made irrigation possible.

Cultivation of water-intensive crops like sugar cane was banned. Crops such as pulses, oil-seeds, and certain cash crops with low water requirements were grown. The farmers started growing high-yield varieties of crop and the cropping pattern of the village was changed. Hazare has helped farmers of more than 70 villages in drought-prone regions in the state of Maharashtra since 1975. When Hazare came in Ralegan Siddhi in 1975 only of land was irrigated, Hazare converted it into about .

Milk production

As a secondary occupation, milk production was promoted in Ralegan Siddhi. Purchase of new cattle and improvement of the existing breed with the help of artificial insemination and timely guidance and assistance by a veterinarian resulted in an improvement in the cattle stock, increasing production of milk. Crossbred cows are replacing local ones which gave a lower milk yield.

Education

In 1932, Ralegan Siddhi got its first formal school, a single classroom primary school. In 1962, the villagers added more classrooms through community volunteer efforts. By 1971, out of an estimated population of 1,209, only 30.43% were literate (72 women and 290 men). Boys moved to the nearby towns of Shirur and Parner to pursue higher education, but due to socioeconomic conditions, girls could not do the same and were limited to primary education. Hazare, along with the youth of Ralegan Siddhi, worked to increase literacy rates and education levels. In 1976 they started a pre-school and a high school in 1979. The villagers formed a charitable trust, the ''Sant Yadavbaba Shikshan Prasarak Mandal'', which was registered in 1979.

Removal of untouchability

The social barriers and discrimination that existed due to the caste system in India have been largely eliminated by Ralegan Siddhi villagers. It was Hazare's moral leadership that motivated and inspired the villagers to shun untouchability and caste discrimination. Marriages of Dalits are held as part of community marriage program together with those of other castes. The Dalits have been integrated into the social and economic life of the village. The upper caste villagers have built houses for the lower caste Dalits by ''shramdaan'' and helped to repay their loans to free them from their indebtedness.

Collective marriages

Most rural poor get into a debt trap as they incur heavy expenses at the time of marriage of their daughter or son. It is an undesirable practice but has almost become a social obligation in India. Ralegan's people have started celebrating marriages collectively. Joint feasts are held, where the expenses are further reduced by the ''Tarun Mandal'' taking responsibility for cooking and serving the food. The vessels, the loudspeaker system, the mandap, and the decorations have also been bought by the ''Tarun Mandal'' members belonging to the oppressed castes. From 1976 to 1986, 424 marriages have been held under this system.

Gram Sabha

The Gandhian philosophy on rural development considers the Gram Sabha as an important democratic institution for collective decision making in the villages of India. Hazare campaigned between 1998 and 2006 for amending the Gram Sabha Act, so that the villagers have a say in the development works in their village. The state government initially refused, but eventually gave in due to public pressure. As per the amendments, it is mandatory to seek the sanction of the Gram Sabha (an assembly of all village adults, and not just the few elected representatives in the gram panchayat) for expenditures on development works in the village.

Activism

Anti-corruption protests in Maharashtra

In 1991 Hazare launched the ''Bhrashtachar Virodhi Jan Aandolan'' (BVJA) (People's Movement against Corruption), a popular movement to fight against corruption in Ralegaon Siddhi. In the same year he protested against the collusion between 40 forest officials and timber merchants. This protest resulted in the transfer and suspension of these officials.

In May 1997 Hazare protested against alleged malpractices in the purchase of powerlooms by the Vasantrao Naik Bhathya Vimukt Jhtra Governor P. C. Alexander. On 4 November 1997 Gholap filed a defamation suit against Hazare for accusing him of corruption. He was arrested in April 1998 and was released on a personal bond of . On 9 September 1998 Hazare was imprisoned in the Yerawada Jail to serve a three-month sentence mandated by the Mumbai Metropolitan Court. The sentencing caused leaders of all political parties except the BJP and the Shiv Sena came in support of him. Later, due to public protests, the Government of Maharashtra ordered his release from the jail. After release, Hazare wrote a letter to then chief minister Manohar Joshi demanding Gholap's removal for his role in alleged malpractices in the Awami Merchant Bank. Gholap resigned from the cabinet on 27 April 1999.

In 2003 corruption charges were raised by Hazare against four NCP ministers of the Congress-NCP government. He started his fast unto death on 9 August 2003. He ended his fast on 17 August 2003 after then chief minister Sushil Kumar Shinde formed a one-man commission headed by the retired justice P. B. Sawant to probe his charges. The P. B. Sawant commission report, submitted on 23 February 2005, indicted Sureshdada Jain, Nawab Malik, and Padmasinh Patil. The report exonerated Vijaykumar Gavit. Suresh Jain and Nawab Malik resigned from the cabinet in March 2005.

Three trusts headed by Anna Hazare were also indicted in the P. B. Sawant commission report. spent by the ''Hind Swaraj Trust'' for Anna Hazare's birthday celebrations was concluded by the commission as illegal and amounting to a corrupt practice, though Abhay Firodia, an industrialist subsequently donated to the trust for that purpose. The setting apart of 11 acres of its land by the trust in favour of the Zilla Parishad without obtaining permission from the charity commissioner was concluded as a case of maladministration. The commission also concluded that the maintenance of accounts of the ''Bhrashtachar Virodhi Janandolan Trust'' after 10 November 2001 had not been according to the rules and spent by the ''Sant Yadavbaba Shikshan Prasarak Mandal Trust'' for renovating a temple was in contravention to its object of imparting secular education.

Right to Information movement

In the early 2000s Hazare led a movement in Maharashtra state which forced the state government to enact a revised Maharashtra Right to Information Act. This Act was later considered as the base document for the Right to Information Act 2005 (RTI), enacted by the Union Government. It also ensured that the President of India assented to this new Act.

On 20 July 2006 the Union Cabinet amended the Right to Information Act 2005 to exclude the file noting by the government officials from its purview. Hazare began his fast unto death on 9 August 2006 in Alandi against the proposed amendment. He ended his fast on 19 August 2006, after the government agreed to change its earlier decision.

Regulation of Transfers and Prevention of Delay in Discharge of Official Duties Act

Before 2006 in the state of Maharashtra, even honest government officers were transferred to other places according to ministers wish. Sometimes within months of being posted to a place, whereas some corrupt and favoured officials were cozy in their postings for many years in some cases even for 10 to 20 years and since there was not any guideline or law many government officials were reluctant to process files that contained important public proposals and decisions. Anna fought hard for a law whereby a government servant must clear a file within a specified time and that transfers must take place only after three years. After many years of relentless efforts of Anna, finally on 25 May 2006 state government of Maharashtra issued a notification announcing that the execution of the special act, The Prevention of Delay in Discharge of Official Duties Act 2006, aimed at curbing the delay by its officers and employees in discharging their duties. This act provides for disciplinary action against officials who move files slowly and enables monitoring officials who stay too long in a post, or in a department, and for involvement in a corrupt nexus. Within this act, it is mandatory for the government to effect transfers of all government officers and employees, except Class IV workers, after the stipulated three years. Act also prevents the government from effecting frequent transfers of officers before the stipulated three-year tenure, except in case of emergency and under exceptional circumstances. Maharashtra is the first state in the country to have introduced such act.

Campaign against liquor from food grains

Constitution of India Article 47 commits the State to raise the standard of living and improve public health, and prohibit the consumption of intoxicating drinks and drugs injurious to health.

In 2007 Maharashtra Government rolled out the grain-based liquor policy aimed to encourage production of liquor from food grain in the light of the rising demand for spirit – used for industrial purposes and potable liquor and Issue 36 licenses for distilleries for making alcohol from food grains. One of the State ministers Laxman Dhoble said in his speech that those opposing the decision to allow use of food grains for the production of liquor are anti-farmers and those people should be beaten up with sugarcane sticks. Hazare initiated fast at Shirdi, but on 21 March 2010 government promised to review the policy and Anna ended his 5 day long fast. But the government later granted 36 licences and grants of (per litre of alcohol) to politicians or their sons who were directly or indirectly engaged in making alcohol from foodgrains. Some of the main beneficiaries of these licences includes Amit and Dheeraj Deshmukh, sons of Union Heavy Industries Minister Vilasrao Deshmukh, Bharatiya Janata Party leader Gopinath Munde's daughter Pankaja Palwe and her husband Charudatta Palwe, sons-in-law of P.V. Narasimha Rao, Rajya Sabha MP Govindrao Adik. The government approved the proposal for food grain-based alcohol production in spite of stiff opposition from the planning and finance departments saying there is a huge demand in other countries for food grain made liquor in comparison with that of molasses. Anna filed a Public Interest Litigation against the Government of Maharashtra for allowing food-grains for manufacturing liquor in the Nagpur bench of the Bombay High Court. On 20 August 2009 Maharashtra government stopped the policy. However, distilleries sanctioned before that date and those who started production within two years of sanction were entitled for subsidies.

On 5 May 2011 court refused to hear a Public Interest Litigation saying "not before me, this is a court of law, not a court of justice" as a reason of not hearing the plea. One of Principal Secretary in Maharashtra state C.S. Sangeet Rao, enlighten that there is no law exists to scrap these licences as this is a government policy. These include placing "the Prime Minister within the ambit of the proposed lokpal’s powers".

Hunger strike in Delhi

Hazare began his Indefinite Fast on 5 April 2011 at Jantar Mantar in Delhi to press for the demand to form a joint committee of the representatives of the Government and the civil society to draft a stronger anti-corruption bill with stronger penal actions and more independence to the ''Lokpal'' and ''Lokayukta''s (Ombudsmen in the states), after his demand was rejected by the Prime Minister of India Manmohan Singh. He stated, "I will fast until Jan Lokpal Bill is passed".

The movement attracted attention in the media, and thousands of supporters. Almost 150 people reportedly joined Hazare in his fast. Social activists, including Medha Patkar, Arvind Kejriwal, former IPS officer Kiran Bedi, and Jayaprakash Narayan lent their support to Hazare's hunger strike and anti-corruption campaign. People have shown support in internet social media such as Twitter and Facebook. In addition to spiritual leaders Sri Sri Ravi Shankar, Swami Ramdev, Swami Agnivesh and former Indian cricketer Kapil Dev, many celebrities showed their public support through Twitter. Hazare decided that he would not allow any politician to sit with him in this movement. Politicians like Uma Bharti and Om Prakash Chautala were shooed away by the protesters when they came to visit the site where the protest was taking place. On 6 April 2011 Sharad Pawar resigned from the ''group of ministers'' formed for reviewing the draft Lokpal bill 2010.

Protests spread to Bangalore, Mumbai, Chennai, Ahmedabad, Guwahati, Shillong, Aizawl and a number of other cities in India.

End of hunger strike after meeting demands

On 8 April 2011 the Government of India accepted all demands of the movement. On 9 April 2011 it issued a notification in the Gazette of India on formation of a joint committee. It accepted the formula that there be a politician Chairman and an activist, non-politician Co-Chairman. According to the notification, Pranab Mukherjee will be the Chairman of the draft committee while Shanti Bhushan will be the co-chairman. “The Joint Drafting Committee shall consist of five nominee ministers of the Government of India and five nominees of the civil society. The five nominee Ministers of the Government of India are Pranab Mukherjee, Union Minister of Finance, P. Chidambaram, Union Minister of Home Affairs, M. Veerappa Moily, Union Minister of Law and Justice, Kapil Sibal, Union Minister of Human Resource and Development and Minister of Communication and Information Technology and Salman Khursheed, Union Minister of Water Resources and Minister of Minority Affairs. The five nominees of the civil society are Anna Hazare, N. Santosh Hegde, Shanti Bhushan Senior Advocate, Prashant Bhushan, Advocate and Arvind Kejriwal.

On the morning of 9 April 2011 Hazare ended his 98-hour hunger strike. He addressed the people and set a deadline of 15 August 2011 to pass the Lokpal Bill in the Indian Parliament.

Anna Hazare said that if the bill does not pass he will call for a mass nation-wide agitation. He called his movement as "second struggle for independence" and he will continue the fight.

Differences with the government on draft bill

During the meeting of the joint drafting committee on 30 May 2011, the Union government members opposed the inclusion of the prime minister, higher judiciary and the acts of the MPs under the purview of the Lokpal in the draft bill. On 31 May 2011, Pranab Mukherjee, chairman of the joint drafting committee sent a letter to the chief ministers of all states and the leaders of the political parties seeking their opinion on six contentious issues in the proposed Lokpal Bill, including whether to bring the prime minister and judges of Supreme Court and High Courts under the purview of the proposed law. But the civil society members of the drafting committee considered that keeping the prime minister and judges of Supreme Court and High Courts out of the purview of the Lokpal would be a violation of the United Nations Convention against Corruption.

Anna Hazare and other civil society members decided to boycott the meeting of the joint Lokpal Bill drafting committee scheduled on 6 June 2011 in protest against the forcible eviction of Swami Ramdev and his followers by the Delhi Police from Ramlila Maidan on 5 June 2011, while they were on hunger strike against the issues of black money and corruption and doubting seriousness of the government in taking measures to eradicate corruption.

On 6 June 2011, the members of the civil society of the joint Lokpal bill drafting committee in New Delhi sent a letter to Pranab Mukherjee, the chairman of the committee, explaining reasons for their absence at the meeting and also asked government to make its stand public on the contentious issues related to the proposed draft legislation. They also decided that the future meetings will be attended only if they were telecast live. On 8 June 2011 at Rajghat, describing his movement as the second freedom struggle, Anna criticised the Government for trying to discredit the joint Lokpal Bill drafting committee and threatened to go on indefinite fast again from 16 August 2011 if the Lokpal Bill is not passed by then. He also criticised the Government for putting hurdles in the drafting of a strong Lokpal Bill and its attempts to malign the civil society members of the joint Lokpal panel.

Indefinite fast

On 28 July 2011 the union cabinet on approved a draft of the Lokpal Bill, which keeps the Prime Minister, judiciary and lower bureaucracy out of the ambit of the proposed corruption ombudsman Lokpal. Hazare rejected the government version by describing it as “cruel joke’’ and wrote a letter to Prime Minister Manmohan Singh, and told him his decision to go on an indefinite fast from 16 August 2011 at Jantar Mantar if the government introduced its own version of the bill in Parliament without taking suggestions from civil society members.

Within twenty four hours of cabinet's endorsement of a weak Lokpal Bill, over ten thousand peoples from across the country sent faxes directly to the government demanding a bill with stronger provisions. The Mumbai Taxi Men’s Union, comprises over 30,000 taxi drivers have extended their full support to Hazare’s fast by keeping all taxis off the roads on 16 August 2011. Lawyers of Allahabad High Court described Lokpal Bill proposed by the government as against the interest of the country and pledged their support to Hazare by hunger strike at Allahabad on 16 August 2011. On 30 July 2011 Vishwa Hindu Parishad supported Hazare's indefinite fast by saying movement for an effective anti-corruption ombudsman needs the backing of people.

On 1 August, Public interest litigation was filed in the Supreme Court of India by Hemant Patil, a Maharashtra-based social worker and businessman, to restrain Hazare from going on his proposed indefinite fast. The petitioner demanded to prohibit the fast alleging that Hazare's demands are unconstitutional and amount to interference in legislative process.

Arrest and aftermath

On 16 August 2011, Hazare was arrested four hours before the planned indefinite hunger strike. Rajan Bhagat, spokesman for Delhi Police, said police arrested Hazare under a legal provision that bans public gatherings and protests at the park in Delhi where he was planning to begin his hunger strike. Police took that action after Hazare refused to meet the conditions put forward by police for allowing the protest. The conditions included restricting the length of the fast to three days and the number of protesters at the site to 5,000. Later in the afternoon, Anna was produced before a magistrate who offered him bail but Anna Hazare refused to provide the bail bond. The magistrate sent him judicial custody for seven days and he was taken to Tihar jail. After announcements by Prashant Bhushan, local television, and social media sites (including Facebook), a march of thousands in support of Hazare began from the India Gate to Jantar Mantar.

Along with Hazare, other key members of the India Against Corruption movement including Arvind Kejriwal, Shanti Bhushan, Kiran Bedi and Manish Sisodia were also detained from different locations. It was reported that about 1,300 supporters were detained in Delhi. Media also reported that the arrest sparked off protests with people courting arrests in different parts of the country. The opposition parties in the country came out against the arrest, likening the government action to the emergency imposed in the country in 1975. Both the houses of Parliament were adjourned over the issue.

Eventually, after being kept in judicial detention for just four hours, he was released unconditionally without any bail bond by the magistrate on a request by the police, but Hazare refused to leave Tihar Jail. He demanded an unconditional permission from the police to observe a fast at Ramlila Maidan (Ground) in support of the Jan Lokpal bill and refused to leave the jail. Hazare continued his fast inside the jail and refused to leave the jail though the jail authorities had technically ''released'' him.

After his arrest, Anna Hazare received support from people across the country. There were reports of "nearly 570 demonstrations and protests by Anna supporters across the country" against the government's imprisonment of Hazare and others. Due to the nationwide protests of millions, the government agreed to allow him to begin a public hunger strike of fifteen days. After talks with public authorities, Hazare decided to hold his protest at Ramlila Maidan, New Delhi. On 20 August 2011 Hazare "left the Tihar Jail for the Ramlila Grounds". Hazare promised reporters "he would fight to the 'last breath' until the government gets his team's Jan Lokpal Bill passed in this session of Parliament, which ends on 8 September."

Fast at Ramlila Maidan, New Delhi

On 20 August 2011 thousands came to the Ramlila Maidan in New Delhi to show their support for Hazare, while "his advisers made televison appearances to rally public support and defend themselves against criticism that their protest campaign and refusal to compromise is undermining India's parliamentary process." The National Campaign for People’s Right to Information (NCPRI) condemned Hazare's deadline for passing the bill as undermining democracy, which operates by "holding wide-ranging consultations and discussions, allowing for dissent and evolving a consensus. ...He [Hazare] has the right to protest and dissent. But nobody can claim it as an absolute right and deny the right of dissent to others." The Congress party confirmed that Maharashtra Additional Chief Secretary (Home) Umesh Chandra Sarangi (who has a history of mediating between Hazare and government officials) was meeting with the social activist again "to find points of consensus and defuse the situation". On 21 August 2011 "tens of thousands" came to Ramlila Maidan to support Hazare as he sat on an elevated platform. It was reported that Hazare at that point had "lost more than seven pounds since beginning his fast", despite this he stated "'I will not withdraw my hunger strike until the Jan Lokpal bill is passed in the Parliament. I can die but I will not bend.'" Hazare ended his fast on 28 August 2011, after the Indian Government had passed the resolution for the Lokpal Bill unanimously,

He was admitted to Medanta Medicity, Gurgaon for post-fast care. He had lost 7.5 kg and was very dehydrated after the 288 hour long fast.

I Am Anna Chant

Within a few days of Anna Hazare's first fast demanding a strong Lokpal (on 5 April 2011), supporters across various cities of India started a campaign known as "I Am Anna Hazare", which is similar to the "We Are All Khaled Said" campaign well known in the Egyptian uprising. At during Anna Hazare's second fast, the ''topi'', the cap which Anna Hazare became synonymous with, became almost a fashion statement. Sales of the topis hit an all time high. Kiran Bedi declared that the "I am Anna" topi should be used as a deterrence method whenever someone asked for a bribe. She went to say that the topi should be always kept in one's bag and whenever anybody ask for a bribe, the topi should be shown to them.

Fast on MMRDA ground

On 27 December 2011, Hazare began a 3 day hunger strike at MMRDA grounds, Bandra Kurla Complex in demand to a stronger version of the Lokpal bill than the is in debate in the Parliament of India. Hazare ended the fast on 28 December 2011, after his doctors said that his kidneys might fail if he continued his fast.

Before reaching the venue, Anna payed his tributes to Mahatma Gandhi at Juhu Beach. On his way in a rally, which was joined by several thousand people, he took two-and-half hours to reach the ground, passing through Santacruz, Tulip Star Hotel, Mithibai College, SV Road, Vile Parle, Khar and Bandra Highway.

Reiterating Anna Hazare's position, a PIL petition filed against the fast was turned down by the Karnataka High Court. A judge also noted that there was no public interest in the petition.

Electoral reform movement

In 2011, Anna Hazare demanded an amendment to the electoral law to incorporate the option of None of the above in the electronic voting machines during the Indian elections. The "None of the above (NOTA)" is a ballot option that allows an electorate to indicate disapproval of all of the candidates in an electoral system, in case of non-availability of any candidate of his choice, as his Right to Reject. Soon, the Chief Election Commissioner of India Shahabuddin Yaqoob Quraishi supported Hazare's demand for the electoral reforms.

Protest against atrocities against Swami Ramdev and his supporters

On 8 June 2011, Anna Hazare and thousands of his supporters observed fast from 10 am to 6 pm at Rajghat to protest against the midnight crackdown of 5 June 2011 by the Delhi Police on Swami Ramdev’s fast at Ramlila Maidan, New Delhi. The fast was initially planned to be held at Jantar Mantar, but the venue was shifted after the denial of permission by the Delhi police. Anna Hazare held the Prime Minister of India responsible for the atrocities and termed the police action as a blot on humanity and an attempt to stifle democracy. According to one of the Anna's young supporters, the large presence of youths in the protest was due to their support to his use of nonviolence means of protest similar to Gandhi.

Controversies and criticism

RSS Agent

Anna Hazare has often being criticized for being an agent of Rashtriya Swayamsevak Sangh a right-wing Hindu body in India. United Progressive Alliance,the present ruling government in India has seldom charged Hazare with it. According to Digvijay Singh a senior leader of the Indian National Congress the entire crusade of 2011 Indian anti-corruption movement is a process being planned by Rashtriya Swayamsevak Sangh in which Plan-A was Baba Ramdev while Plan-B was Anna Hazare. Their basic job was to disturb the national security of the country. Further Digvijay Singh had charged Anna Hazare for having links with late Rashtriya Swayamsevak Sangh leader Nanaji Deshmukh with whom he worked as a secretary. However Anna has declined for having any such associations.

Views on Narendra Modi

In a press conference in April 2011, Anna Hazare praised Narendra Modi, the chief minister of Gujarat for his efforts on rural development along with Nitish Kumar, chief minister of Bihar, saying that the same should be emulated by the chief ministers of all states. Subsequently, Modi wrote an open letter to him, hailing him as a Gandhian and anti-corruption activist while Digvijay Singh, the General Secretary of the Congress party, criticised him for his comment. In May 2011, Hazare, during his visit to Gujarat, changed his view and criticised Modi for rampant corruption by Government officials in Gujarat. He urged Modi to appoint a Lokayukta in Gujarat. He also commented that the media had projected an incorrect image of Vibrant Gujarat, very different from the prevalent situation.

Fraud during fasts

A cardiologist from Pune, Abhijit Vaidya – founder of Arogya Sena, a non-governmental agency active in public health, disaster management and social campaigns – claimed that he was informed by the close associates of Anna Hazare during a fast in Ralegan-Siddhi, that he was given glucose and electrolyte solutions during a fast. Hazare and his associates refused to comment on the allegation.

Accusations of corruption

The government of the state of Maharashtra instituted a Commission of Inquiry under Justice PB Sawant in September 2003 to enquire into allegations of corruption against several people, including four ministers in the state as well as the "Hind Swaraj Trust" headed by Hazare. The Commission submitted its report on 22 February 2005 in which it indicted the Hind Swaraj Trust for corrupt practice of spending Rs. 2.20 lakhs of its funds on the birthday celebrations of Hazare. Two days ahead of Hazare's proposed indefinite fast on 16 August 2011, the ruling party of India, the Indian National Congress, launched an attack on him alleging that "the moral core of Hazare has been ripped apart" by the Justice P B Sawant Commission.

In response to this allegaton, Hazare's lawyer Milind Pawar, claimed that the commission had remarked about "irregularities" in the accounts, but had not held him guilty of any "corrupt" practices. Pawar said that on 16 June 1998, a celebration was organised to facilitate Hazare on winning an award from a US based NGO and it coincided with his 61st birthday. The trust spent Rs 2.18 lakh for the function. Abhay Phirodia, a Pune-based industrialist, who took the initiative to organise this function donated an amount of Rs 2,48,950 to the trust by cheque soon after the function.

Hazare himself responded to the allegation by daring the government to file a First Information Report (FIR) against him to prove the charges.

Accusation of being anti-democratic and anti-dalit

An article written in The Telegraph (Kolkata) by writer and historian Ramchandra Guha state that that environmental journalist Mukul Sharma found that that Anna Hazare forced the Dalit families in Ralegan Siddhi to adopt a vegetarian diet, and that those who violated the decree were tied to a post and flogged. Mukul Sharma also found that no panchayat elections have been held in the village for the past two decades, and that no campaigning was allowed during state and national elections, upon the instructions of Anna Hazare. Another activist Anoop Kheri claimed that "The language, symbols used by the movement clearly reflects its upper caste Hindu nature, a very rightwing Hindu patriotism is being used to get the entire country against corruption. And as a dalit, I have a problem with it."

There was also an allegation that an RTI activist was denied permission to protest by having a fast-unto-death at Ralegan Siddhi, the grama sabha stating that the reason was that only Anna Hazare can hold such fasts in his village.

During his protest against corruption, another activist, Udit Raj, who was denied permission to protest against Anna Hazare, warned that succumbing to Hazare's demands, which he claimed were against the parliamentary processes will set a dangerous trend rendering the backward classes more vulnerable, as such mass mobilisations coercing the government with a "set of solutions" against constitutional processes could also be used against affirmative action, and is a threat to democracy. Later, it came to light that poor dalits had been paid money of up to 200 each, exploiting their desperation. The participants said that they were asked to shout slogans against Anna, although the organizers have denied it. Some protesters said that they had been told that it was a pro-Anna protest, but feel cheated after realising that it was against Anna hazare.

Accusation of being nonsecular

On 22 August 2011 writer-actor Arundhati Roy accused Hazare in a newspaper article of being nonsecular. She questioned his secular credentials pointing out Hazare's "support for Raj Thackeray's Marathi Manoos xenophobia and (has praised) the 'development model' of Gujarat's CM who oversaw the 2002 pogrom against Muslims". The website of the newspaper published many responses to her article and these were mostly critical of her views. Activist Medha Patkar also strongly criticised Roy, saying that her views were misplaced.

Hazare has in the past stood in firm opposition to the Shiv Sena and BJP governments in Maharashtra. Activist and writer Asghar Ali Engineer in an EPW article on Communalism and Communal Violence reported,

Hazare was accused of working for RSS and BJP's behest, and against Muslims by cleric Bukhari of the Jama Masjid. Bhukhari was subsequently criticised for being a Royal Imam and the communal comments being his personal views which did not represent the view of ordinary Muslims.

Anna supports violence selectively

Hazare acknowledged his belief in violence after his remark "just one slap" in which the victim of violence was Sharad Pawar, a rival in maharashtra in terms of popularity.

Conspiracy to murder Hazare

Anna Hazare has exposed large corruption in co-operative sugar factories of Maharashtra. One of the sugar factories which Anna exposed corruption of is controlled by Dr.Padamsinh Bajirao Patil, a member of Parliament of 15th Lok Sabha and higher-ranking Leader of Nationalist Congress Party from Osmanabad, and also a prime accused and conspirator in the 2006 murder case of Indian National Congress leader Pawanraje Nimabalkar.

The conspiracy to kill Hazare was exposed when Parasmal Jain, an accused in the Nimbalkar murder case, in his written confession before a magistrate said that Padamsinh Bajirao Patil had paid a sum of to murder Nimbalkar, and also offered him supari (contract killing sum) to kill Anna Hazare. After this written confession, Anna appealed to the state government of Maharashtra to lodge a separate First Information Report ( FIR ) against Padamsinh Bajirao Patil for conspiring to murder him but the government did not take any action in this regard. Anna Hazare decided to lodge a complaint himself and on 26 September 2009, he lodged complaint at Parner police station of Ahmednagar District in Maharashtra against the Nationalist Congress Party (NCP) MP Padamsinha Patil for conspiring to eliminate him. Padamsinh Patil approached the High Court seeking anticipatory bail but on 14 October 2009, the Aurangabad bench of Bombay High Court rejected the anticipatory bail application of Padamsinh Patil in connection with a complaint filed by Anna after observing that there is a prima facie evidence against him.

Padmasinh Patil appealed for an anticipatory bail in Supreme Court of India which the court rejected on 6 November 2009. On 11 November 2009 Padmasinh Patil surrendered before the sessions court in Latur as per a directive of the Supreme Court and was sent to judicial remand for 14 days. On 16 December 2009 Aurangabad bench of Bombay High Court granted bail to him. , the verdict is pending.

As of December 2011, Anna Hazare has got Z+ security.
