  Energy - Wikipedia, the free encyclopedia
Free energy is a useful concept in chemistry, because energy considerations alone are not sufficient to decide the possibility of a chemical reaction.
Energy diffusion from more to less concentrated forms (net increase in entropy for the universe) is the driving force of all biological processes as all biochemical processes are a subset of chemical processes.
Energy is subject to the law of conservation of energy (which is a mathematical restatement of shift symmetry of time).

 Category:Energy - Wikipedia, the free encyclopedia
Energy is a quantifiable state function of every physical system.
Energy allows one to predict how much work a physical system could be made to do, or how much heat it can exchange.
In general, the presence of energy is detected by an observer or system any time there is a change in the properties of another object or system.

 Energy, by Robert A. Leone: The Concise Encyclopedia of Economics: Library of Economics and Liberty
Energy is not a single industry, but many industries tied into every facet of our economy, from transportation and manufacturing to home heating and lighting.
Such discussions are dominated by concerns about energy depletion and the limits to economic growth, the belief of many in the need for regulation of energy markets, and the exaggeration or misstatement of the political hurdles that must be overcome to address the real challenges of energy use in a global economy.
Advocates of a market-oriented energy policy believe that a major part of the increase in miles per gallon was due to gasoline prices that were much higher in the late seventies and early eighties than in the late sixties and early seventies.

Energy Conversion Law...in any particular process of converting external energy to internal energy or internal energy to external energy, if any temperament produced is less than the maximum possible for that process, there will be a loss of exergic energy in that process.
Such a common study of energy could be called energy science which does not cover specific details of all of science but rather only the ones specifically relating to the concepts of energy.
While it is definitely considered to be a form of external energy, it appears to be a form of thermal energy and obeys many of the same gas rules as thermal energy.

/2 is the kinetic energy, the energy of motion.
The rate at which energy is supplied or used is called power and is measured in watts, after the inventor of the modern steam engine, the Scotsman James Watt (1736-1819): an energy supply providing one joule per second gives one watt of power.
It would solve all of mankind's energy problems if, for instance, one could extract the heat energy of the oceans, leaving them slightly cooler and converting the extracted heat to electricity; but the second law tells that it cannot be done.

 Energy: a guide for kids by Tiki the Penguin
Energy means that birds can fly, tigers can roar, wind can blow, sun can shine, cars can go fast, factories can make things, light bulbs can glow and your computer can work.
This means you get your energy from eating plants, or by eating other animals like cows which have fed off plants.
You get this energy mostly by digging it out of the ground, releasing ancient energy stores - fossil fuels - made by billions of tiny plants and stored by animals which lived millions of years ago.
