Abstract

The geothermal gradient delivers about 61.5 mW/m2 from the interior of the Earth to the surface. Since the surface area of the Earth¼5.1_108 km2, the rate at which energy is released from the interior of the Earth is 3.1_1010 kW. The solar power that impinges on the Earth is 342W/m2. If all of this were absorbed, the Earth would receive 1.7_1014 kW. Actually, only about 70% of the incident solar energy is absorbed by the Earth; nevertheless, the solar input far exceeds that which derives from the interior. Therefore geothermal energy may be ignored in dealing with the heat balance of the Earth.
