Water is heated, turns into steam and spins a steam turbine which drives an electrical generator . After it passes through the turbine, the steam is condensed in a condenser . The greatest variation in the design of steam - electric power plants is due to the different fuel sources . </P> <P> Almost all coal, nuclear, geothermal, solar thermal electric power plants, waste incineration plants as well as many natural gas power plants are steam - electric . Natural gas is frequently combusted in gas turbines as well as boilers . The waste heat from a gas turbine can be used to raise steam, in a combined cycle plant that improves overall efficiency . </P> <P> Worldwide, most electric power is produced by steam - electric power plants, which produce about 86% of all electric generation . The only other types of plants that currently have a significant contribution are hydroelectric and gas turbine plants, which can burn natural gas or diesel . Photovoltaic panels, wind turbines and binary cycle geothermal plants are also non-steam electric, but currently do not produce much electricity . </P>

In an electric power plant turbines are turned using which type of energy from steam
