Many countries around the world depend on power plants to generate electrical energy. A power plant is a station where energy is produced through a full operation of manpower and generators which generate electric energy. Power plants use a process of transforming mechanical energy to electric energy so as to supply power for the communal use. In order to produce energy in a power plant there must be a fuel to establish the mechanical energy like coal, natural gas, petroleum or uranium. Energy can be generated through the flow of water or wind as well as to geothermal and tidal sources.
