In physics, energy (from Ancient Greek: ἐνέργεια, enérgeia, “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The Earth's climate and ecosystems processes are driven by the energy the planet receives from the Sun (although a small amount is also contributed by geothermal energy).
internal or inherent power; capacity of acting, operating, or producing an effect, whether exerted or not; as, men possessing energies may suffer them to lie inactive
power efficiently and forcibly exerted; vigorous or effectual operation; as, the energy of a magistrate
strength of expression; force of utterance; power to impress the mind and arouse the feelings; life; spirit; -- said of speech, language, words, style; as, a style full of energy
capacity for performing work
In physics, energy is an indirectly observed quantity which comes in many forms, such as kinetic energy, potential energy, radiant energy, and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects, and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple, intuitive way, although energy can be rigorously defined in theoretical physics. In the words of Richard Feynman, "It is important to realize that in physics today, we have no knowledge what energy is. We do not have a picture that energy comes in little blobs of a definite amount." However, it is clear that energy is always an indispensable prerequisite for performing mechanical work, and the concept has great importance in natural science. The natural basic units in which energy is measured are those used for mechanical work; they always are equivalent to a unit of force multiplied by a unit of length. Other equivalent units for energy are mass units multiplied by velocity units squared.
Chambers 20th Century Dictionary
en′ėr-ji, n. power of doing work: power exerted: vigorous operation: strength: (physics) the term, as applied to a material system, used to denote the power of doing work possessed by that system.—adjs. Energet′ic, -al, having or showing energy: active: forcible: effective.—adv. Energet′ically.—n.pl. Energet′ics, the science of the general laws of energy.—adj. Ener′gic, exhibiting energy.—v.t. En′ergise, to give strength or active force to.—v.i. to act with force:—pr.p. en′ergīsing; pa.p. en′ergīsed.—Conservation of energy (see Conservation). [Gr. energeia—en, in, ergon, work.]
The Standard Electrical Dictionary
The capacity for doing work. It is measured by work units which involve the exercise of force along a path of some length. A foot-pound, centimeter-gram, and centimeter-dyne are units of energy and work. The absolute unit of energy is the erg, a force of one dyne exercised over one centimeter of space. (See Dyne.) The dimensions of energy are force (M * L / T^2) * space (L) = M * (L^2 / T^2). Energy may be chemical (atomic or molecular), mechanical, electrical, thermal, physical, potential, kinetic, or actual, and other divisions could be formulated.

Inspector General Setyo Wasisto:
They( bootleggers and their distributors) are part of a close knit community. Sometimes, when police come to check on a tip they have already put the bootleg alcohol away. They know who their customers are when they come. It's much like a clandestine narcotics network, in the past, bootleg alcohol was found to be a mixture of alcohol and energy drinks. Some are a mix of pure alcohol, carbonated drinks and an ingredient used in anti-mosquito repellent.
