1. ENERGYnoun

   Etymology: ἐνέϱγεια.

1. Energy

   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).

1. energy

   Energy is a fundamental concept in physics that refers to the capacity of a system to do work or produce a change. It can exist in different forms, such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (energy due to temperature), chemical energy (energy stored in chemical bonds), and many others. Energy can be converted from one form to another, but it is never created or destroyed, following the law of conservation of energy.

1. Energy

   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.

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 DictionaryRate this definition:5.0 / 3 votes

1. Energy

   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.

1. French President Francois Hollande:

   There is no shortage of (private sector) money to come to energy in Africa, but we have to get the policy and regulatory environment correct.

2. Johnny Stuen:

   When it comes here what we want to do is to burn the rest that is not usable for material recovering because it's too dirty or too mixed or whatever, we want to recover the energy in it because that's still available. So that's when it comes here and we take care of it and burn it up and then we use the energy to district heating and producing electricity.

3. Jaime Alguersuari:

   We have a target (power) consumption per lap and we need to respect that like the Bible, you want to win, but if you burn up all your energy you won't finish.
