ENERGY The ultimate source of geothermal energy is the extremely hot and molten core of the earth. Heat radiating out of the core is lost from the earth’s surface, in the process giving rise to generally increasing temperature with depth. The energy contained in the earth’s core is so vast as to be practically inexhaustible compared to mankind’s energy demand. Geothermal energy would be
