Clean, Reliable and Renewable
Geothermal energy is heat energy that comes from the earth's molten interior deep in the earth's crust. The heat is brought near to the surface due to movements in the earth's crustal plates by intrusion of molten magma and by deep circulation of groundwater. Reservoirs of hot water under pressure are formed.
In some places geothermal energy rises to the surface in natural streams of hot steam or water, which have been used since ancient times for bathing and cooking.
Utilization of this geothermal energy is achieved by drilling wells into these reservoirs to bring such steam from the high pressure hot water, and direct the steam and separated hot water to drive turbines in power plants. The heat energy is thereby converted to electrical energy.
The cooled geothermal fluid is injected back to the reservoir where it is reheated and preserves the resource mass balance and sustainability. The Advantages of Geothermal Energy are Enormous: harnesses a natural locally available energy source provides an environmentally friendly energy alternative avoiding fossil fuel combustion produces no nitrous oxide (NOx) emissions and significantly lower levels of CO2 than conventional fossil fuels baseload electricity 24/7 year-round supply with high reliability as a local energy source, provides security of energy supply and price, reducing need for importation of fuel
Due to the above advantages, geothermal power has become a preferred energy source wherever economically accessible. History of Geothermal Energy in the U.S. For more information on Geothermal Energy: - Geothermal Resources Council (GRC)
