The earth beneath us contains a large amount of energy in the form of heat. This energy is called geothermal energy. Geothermal energy is used to generate geothermal power to provide a large amount of electricity. The production of electricity from geothermal energy is an efficient and powerful method.
The main use of geothermal power is to provide electricity. However, geothermal power systems provide heating and cooling of a building.
The most commonly used geothermal power systems are geothermal ground source heat pumps. These heat pumps penetrate to only the first few meters below the earth’s surface to harness geothermal energy. These systems use the heated ground water to keep the buildings warm in winters when the earth is used as a heat source and cool in summers when the earth is used as a heat sink.
Geothermal power systems can be used in any location where geothermal energy can be found and harnessed easily. The ground source heat pumps can have either one loop or two loops. In a single loop system, heat is exchanged directly with the ground. In a double loop system, heat is exchanged with a secondary loop and then with the ground.
Geothermal power systems are very costly to be installed. However, the efficiency of these systems overtakes the costs of installation of such systems.
Geothermal power can be used in geothermal power systems either to generate electricity or to heat and cool buildings. In both cases, geothermal power offers the best and the most convenient way for doing so.
