An energy carrier is simply any system or substance used to transfer energy from somewhere to somewhere else. For example, If energy from a nuclear power plant is used to produce Hydrogen by electrolyzing water which is then burned in a fuel cell to drive a car, then Hydrogen is the energy carrier moving energy from natural Uranium to the vehicle. This is usually differentiated from "sources" of energy such as coal, oil, natural gas, etc, whose energy was not "put there" by human beings but rather by various natural processes. It is also considered different from energy transmission, i.e. the wires and transformers used to move electricity from power plants to consumers.

The chemical energy of a substance is due to the condition of the atoms of which it is made; it resides in the chemical bonds that join the atoms in compound substances (see chemical bond).
The dominant model of energy policy that emerged from this period and existed unchanged until the 1970s was one of support for conventional resources and regulation of industries whose natural monopolies required some government oversight to ensure that their public purpose served a public interest.
Energy, in the distant past, was discussed in terms of easily observable effects it has on the properties of objects or changes in state of various systems.
