Sources of Clean Energy – Geothermal Energy

Geothermal EnergyGeothermal energy is generated by the heat from the Earth. It can be used as an energy source for large and complex power stations to small and relatively simple pumping systems.Sources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called magma. Geothermal energy can be captured in many ways.

Geothermal energy can be used by geothermal heat pumps to provide heat and cooling for buildings. A geothermal heat pump system consists of a heat pump, an air delivery system, and a heat exchanger. Hot water near the surface of Earth can be used directly for heat. Some of the applications of geothermal energy include heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes such as pasteurizing milk.

Geothermal energy is clean and powerful. The output does not depend on the weather conditions. Geothermal power plants do not occupy too much space and maintenance cost is very low. Geothermal Energy needs access to places which have underground geothermal activity. Thus not all areas are suitable for installation of geothermal plants. Many technologies have been developed to take advantage of geothermal energy. Experts say that existing technologies do not yet allow recovery of heat directly from magma, the very deep and most powerful resource of geothermal energy. Scientists say that in an increasing energy hungry world geothermal resources has an important role to play.
