Where does geothermal energy come from?
Geothermal resources are found in three types of locations: in shallow ground; in the hot water and rock located a few miles beneath the earth’s surface; and even deeper into the earth where molten rock reaches extremely high temperatures.
Today we drill wells into the geothermal reservoirs to bring the hot water and steam to the surface. Geologists and engineers do a lot of exploring and testing to locate underground areas that contain this geothermal resource, so we’ll know where to drill production and injection wells. Once the hot water and/or steam travel up the wells to the surface, they can be used to generate electricity or for other energy-saving purposes.
This heat, called geothermal energy, provides warmth and power without polluting the environment.
