Geothermal energy, is heat that is generated within the Earth.(Geo means “earth,” and thermal means “heat” in Greek.)It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below the Earth’s crust, or surface, is the hottest part of our planet: the core.A small portion of the core’s heat comes from the friction and gravitational pull ...
