Energy sources are forms of potential energy that can be used to perform work. An energy resource is anything that can generate heat, make objects move, and produce electricity. Energy sources are categorised as renewable if they constantly and rapidly renew themselves for steady reliable use. Any other source of energy is considered non –renewable. All living organisms constantly take in and release energy. The Earth’s climate and ecosystems processes are driven primarily by radiant energy from the sun. The energy Industry provides the energy required for human civilization to function, which it obtains from energy resources such as fossil fuels, nuclear fuel, renewable energy, and geothermal energy. The total energy of a system can be subdivided and classified into potential energy, kinetic energy, or combinations of the two in various ways. Kinetic energy is determined by the involvement of an object- or the composite motion of the object components –while potential energy reflects the potential of an object to have motion, generally being based upon the object’s position within a field or what is stored within the field itself.
