A Power station is an industrial facility for the generation of electric power. Most of them contain one or more generators and a rotating machine that converts the rotation movement into electric power. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity, some others also use nuclear power. In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy, often from combustion of a fuel, into rotational energy. Most thermal power stations produce steam, so they are sometimes called steam power stations. Not all thermal energy can be transformed into mechanical power, but there is always heat lost to the environment. If this loss is employed as useful heat, for industrial processes or district heating, the power plant is referred to as a cogeneration power plant.

Types of power stations would be:

• Fossil-fuel power stations may use, gas, coal or oil fire for the turbines or boilers.
