Earth, Lakes, and Building Systems

What is geothermal energy? Ten miles beneath the earth’s surface, an almost limitless source of energy waits to be mined. It’s not oil, coal, or natural gas, but the energy from the rocky, hot interior of 420 °C, or 800 °F, or more. This intense heat, known as geothermal energy, turns underground water into the steam that erupts from geysers. These natural pockets of steam, within a mile of the surface, are too rare to provide large amounts of natural geothermal energy worldwide.
