Most of the electricity in the United States is produced using steam turbines
A turbine converts the kinetic energy of a moving fluid (liquid or gas) to mechanical energy. In a steam turbine, steam is forced against a series of blades mounted on a shaft. The steam rotates the shaft connected to a generator. The generator, in turn, converts its mechanical energy to electrical energy based on the relationship between magnetism and electricity.
In steam turbines powered by fossil fuels (coal, natural gas, and petroleum), the fuel is burned in a furnace to heat water in a boiler to produce steam.
