Most power plants rely on steam to kick off a mechanical process that will ultimately generate electricity. The steam is created by heating some material like water or coal. This steam is then channeled and its pressure moves a turbine. The turbine is connected to a generator, which then produces electricity as the turbine moves. This is a mechanical process that requires a lot of physical equipment, and the reason traditional power plants are so large.
