You are here. Geothermal energy is heat derived below the earthâs surface which can be harnessed to generate clean, renewable energy. This vital, clean energy resource supplies renewable power around the clock and emits little or no greenhouse gases -- all while requiring a small environmental footprint to develop.
Geothermal energy is the heat energy that is found beneath the earth s crust in the mantle layer. The earth is made up of four primary layers; the crust (6-40 miles), the mantle (1800miles), the outer core (1375 miles), and the inner core (1750 miles) (Grolier).
