What is Geothermal Energy?

Geothermal energy is energy that is derived from the temperature of the earth. The earth absorbs 50 percent of all solar energy and traps it as heat just below the frost line. Using a heat pump, this natural and renewable resource trapped below the earth's surface is transformed into a harnessable form of energy. This energy --geothermal energy-- provides buildings with a dependable, eco-friendly and economic heating and cooling system.
