Geothermal energy is energy that is produced by heat from the Earth. This heat results from decaying radioactive elements in the Earth’s mantle. It is estimated that the thermal energy situated within 6 miles of Earth's surface contains 50,000 times more energy than the world’s oil and natural gas reserves. Geothermal energy is acquired by tapping into underground reservoirs of heat that are often, but not necessarily, located near volcanoes, hot springs and geysers. Some geothermal power plants capture steam that naturally vents at these formations. Other plants drill boreholes and pump water into the rock surrounding these geothermal features. In either case, steam is captured in pipes that lead to turbines which turn electrical generators. About 0.4% of America’s electricity is now produced by geothermal energy. Supporters claim geothermal power is clean, sustainable, offers constant output and is grossly underutilized.
