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 (from the Greek roots geo, meaning earth, and thermos, meaning heat) is energy made by heat inside the Earth's crust. It's clean and sustainable.Although the Sun does heat the surface of the Earth, heat from inside the Earth is not caused by the Sun.The geothermal energy of the Earth's crust comes 20% from the original formation of the planet, and 80% from the radioactive decay of minerals.The Earth is hottest at its core and, from the core to the surface, the temperature gets gradually cooler.lthough the Sun does heat the surface of the Earth, heat from inside the Earth is not caused by the Sun. The geothermal energy of the Earth's crust comes 20% from the original formation of the planet, and 80% from the radioactive decay of minerals.
