Geothermal Energy - Essay ExampleUnlike the naturalized method of burning fuels to produce the ignite required, optimizing earths energy from deep within the ground is by nature sustainable and would not take additional chemical substance process to be transformed to a useful form. Moreover, geothermal energy is never likely to contribute to greenhouse effect as fossil fuels be and once put up, the power plant would be self-sustaining or not necessitating external energies aside from the power it yields. Roughly 33,000 feet beneath the earths surface lies heat that contains about fifty thousand times more energy compared to the combined presence of natural gas and oil currently processed by men. This unavoidably fluid heat experiences high temperatures in various zones where layers upon layers of molten rock commonly kn proclaim as magma are continuously formed as a consequence of naturally occurring radioactive elements that undergo intense decomposition on a subatomic level fo r several years. Because magma is less dense than the rocks surrounding it, it rises to the surface. sometimes magma escapes through cracks in the Earths crust, erupting out of volcanoes as part of lava. But most of the time magma stays beneath the surface, heating surrounding rocks and the water that has become trap within those rocks. Sometimes that water escapes through cracks in the Earth to form pools of hot water (hot springs) or bursts of hot water and steam (geysers). The rest of the alter water remains in pools under the Earths surface, called geothermal reservoirs. By the Earths crust shifting and allowing water to mix into natural hot-spots water is superheated and then vented through holes in the Earths surface with tremendous power. The superheated water generated at these locations can naturally reach temperatures of up to 200C (430F). Earths core is nearly 6000C - hot enough to melt a rock. Even a few kilometers down, the temperature can be over 250 C devoted that the Earths crust is thin. Temperature generally rises a degree Celsius for every 30 - 50 meters you go down, but this alters with respect to location. Among the hotspots from which geothermal energy may be obtained are certain states of America as Oregon, California, Alaska, and Nevada which possesses a significant number of volcanoes comprising the Pacific Rim or the Pacific Ring of Fire. Hotspots are typically close to fault lines or young volcanoes were the Earths crust is thin enough to allow internal heat to escape and be accessed by as little bore is possible. It may be a surprising fact to discover that besides these seismically active regions, any other location on earth ranging from a attainment of 10 to a few hundred feet through the crust is capable of heating objects even at lower degrees. The capacity to generate electricity by extracting heat out of these places would of course depend on the quantity of drawn heat which can be converted to electrical energy. Landrell o, in Italy is the first to own a geothermal power station, followed by Wairekei in New Zealand and a few others were built in Iceland, Japan, Indonesia,
