At a geothermal power plant, wells are drilled 1 or 2 miles deep into the Earth to pump steam or hot water to the surface.\
Hot water is pumped from deep underground through a well under high pressure.
When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam.
The steam spins a turbine, which is connected to a generator that produces electricity.
The steam cools off in a cooling tower and condenses back to water.
The cooled water is pumped back into the Earth to begin the process again.
