Flash steam geothermal power plant at the U.S. Navy Air Weapons Station, Ridgecrest, California. The power plant lies within the Coso Geothermal Field. Geothermal steam is tapped from wells drilled deep underground into fractures and faults. The high-pressure steam spins a turbine, which spins a generator, producing electricity. Geothermal power plants return most geothermal fluids to their reservoir rocks deep underground. Geothermal power is essentially pollution free and sustainable, offering many benefits to the environment.
