Energy
The capacity for doing work as measured by the capability of doing work (potential energy) or the conversion of this capability to motion (kinetic energy). Energy has several forms, some of which are easily convertible and can be changed to another form useful for work. Most of the world's convertible energy comes from fossil fuels that are burned to produce heat that is then used as a transfer medium to mechanical or other means in order to accomplish tasks. In the United States, electrical energy is often measured in kilowatt-hours (kWh), while heat energy is often measured in British thermal units (Btu).

This article is about scientific use of the word Energy. For other uses, see Energy (disambiguation). In general, the concept of energy refers to "the potential for causing changes." The word is used in several different contexts. The scientific use has a precise, well-defined meaning, whilst the many non-scientific uses often do not. In physics, energy is mathematically defined as a work done by a certain force (gravitational, electric, magnetic, force of inertia, etc) and usually taken with a negative sign. Due to variety of forces, energy has many different forms (usually named after specific force involved), however these can be broken down into two main forms: kinetic energy and potential energy. According to the above definition, energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example. Lightning is a highly visible form of energy transfer.Melbourne Herald Sun,THE dust is yet to settle on the continuing shake-up of Australia's energy industry.
