Thermionic generators convert heat or light into an electric current by using the temperature difference between two metallic plates that are separated by a vacuum. The hot plate is heated either by incident light or thermal conduction and this causes electrons to evaporate from its surface.
The pressurized steam turns the turbine, which makes electricity. Coal, oil, natural gas, nuclear energy, and wood waste are used to generate electricity in this way. Moving water is funnelled into a turbine, making it turn. The turbine then generates electricity. Most electricity generated in this way comes from hydro-electric dams. These dams hold water back in a reservoir behind a large wall, usually made of concrete.
