'''Energy''' is the ability to do work.<ref>Wile, Dr. Jay L. ''Exploring Creation With [[Chemistry]]''. Apologia Educational Ministries, Inc. 1998</ref> In [[physics]], energy is a conserved quantity, and a closed system of interacting particles is known to always have the same value for its energy; this is known as the law of conservation of energy.<ref>Halliday, Resnick, Walker: '' Fundamentals of Physics'', 6th Edition</ref> The SI unit of energy is [[joule]]. Energy can be converted into various forms like [[Potential energy]], [[Kinetic energy]], Chemical energy and Thermal energy, but it cannot be created or destroyed.

More generally, energy is a source of usable heat or power.
More generally, energy is a source of usable heat or power.
According to the [[Theory of Relativity]] the formula of energy is [[E=mc2]].
According to the [[Theory of Relativity]] the formula of energy is [[E=mc2]]. However this formula is controversial.
