The temperatures deep inside the earth are in the order of hundreds and even thousands of degrees Celsius. The quantity of heat performed to the earth’s surface from this interim in a single year is thought to equal some 100 billions megawatts hours of energy and a lot of occasions the electrical energy applied globe wide an astounding amount of energy indeed. Much of this heat is stored in underground layers of molten rock, or magma. Harnessing this treasure, though, is a challenge. On the other hand, the earth’s heat is certainly a treasure simply because it is a clean source of power that provides distinct advantage more than oil, coal, all-natural gas, and nuclear power.
Geothermal energy is generated in more than 20 nations. The United States is the world’s largest producer, and the largest geothermal development in the globe is The Geysers north of San Francisco in California. In Iceland, a lot of of the buildings and even swimming pools are heated with geothermal hot water. Iceland has at least 25 active volcanoes and quite a few hot springs and geysers.
Another nation in the Asia-Pacific region searching to exploit geothermal energy is PNG, exactly where gold miner Lihir Gold already has a geothermal plant powering mine operations. Bismarck Energy managing director Karl Yalo recently appealed to the PNG government to encourage geothermal energy as high and increasing fossil fuel prices hit the regional economy really hard.
Mexico is a single of the fastest increasing geothermal producers in the world. Twenty-seven geothermal energy plants are operating in the 3 Mexican fields, with total geothermal capacity of 953 MW in December 2005. There is a project to install 75 MW in 2006-2008 in the new region La Primavera pending resolution of some environmental matters. CFE has programmed to increase capacity in Cerro Prieto (one hundred MW) and Los Humeros (25 MW) in 2010.
Geothermal power has been utilized to present heat for as lengthy as people have been around to take advantage of it. For example, in some locations the natural groundwater, heated by this geothermal power, finds its way to surface and emerges in hot springs or steam geysers, which have been utilised by humans for bathing and agriculture because pre-history.…
