Stock photography, photos: Geothermal Energy - Hawaii Stock photos of Geothermal energy is the natural heat of the earth stored deep below the earth's surface. The energy is found near areas where volcanic activity has taken place, either recently or many years ago. It can be in the form of steam, hot liquid, or hot dry rock.
