Geothermal energy is heat energy that is contained and formed in the bowels of the earth. geothermal energy comes from technological activities that exist in the earth that have occurred since the earth was created. Besides, geothermal heat also comes from sunlight that is absorbed by the earth's surface. In addition to the heat sources mentioned earlier, geothermal is thought to originate from the following phenomena:
