Geothermal Energy

Geothermal power stations use the natural heat from the Earth to produce electricity. Holes are drilled into the ground, and hot water is pumped to the surface, where it creates steam used to drive a turbine. Electricity can only be produced this way in specific places where the Earth's crust has trapped hot water and steam underground.

At the moment, there are over 200 of these geothermal power stations in the United States - most of them in California and Nevada.
