A thermal power station is a power station in which heat energy is converted to electric power. In most, a steam-driven turbine converts heat to mechanical power as an intermediate to electrical power. Water is heated, turns into steam and drives a steam turbine which drives an electrical generator. Steam turbine driven generators are commonly used in solar thermal electric power plants, coal, geothermal, nuclear, waste incineration plants and natural gas power plants. They are also used extensively in cement, sugar, steel, paper, chemicals and other industries.
