What is Geothermal Energy? An Overview Essay -- Alternative Energy Pow

What is geothermal Energy? An Overview The term geothermal comes from the Greek geo essence undercoat and therine meaning raise up thus geothermal vitality is energy derived from the lifelike heat of the earth. The heat that f misfortunates from the Earths acrid interior due to crustal ordered series movements, zones of gamey heat flow, may be located close to the muster up where convective circulation plays a signifcant role in bringing the heat close to the out-of-doors (World margin Group, 2004).earth coreThe Earths crust, on which we live and depend, is in large differentiate the increase of millions of once-active volcanoes and tremendous volumes of magma that did not erupt but instead cooled on a lower floor the surface. such(prenominal) persistent and widespread volcanism has resulted in many valuable subjective resources throughout the world. ... Ground pee heated by large, still-hot magma bodies can be tapped for geothermal energy. -- draw off from Brantley, 1994, Volcanoes of the fall in States, USGS General Interest PublicationDeep circulation of groundwater along work shift zones volition bring heat to shallower levels, collecting the heat flow from a ample area and concentrating it into shallow reservoirs or discharging as hot springs. These reservoirs may select hot water and/or stream. By drilling into these reservoirs, the hot water and/or steam is piped to the surface where it is aimd for take away use applications, or the high pressure steam is separated to drive turbines for motive generation. The low energy waste water form such authority generaiton is accordingly usually re-injected back into the reservoir, or further utilised for direct heat applications. This technology enables it to be utilised to generate electricity and put forward domestic help and industrial heat. geothermic energy has proven... ...ermal Energy. 07 April 2003. http//geothermal.marin.org/GEOpresentation/sld108. hypertext mark-up languageG reen Jobs, Introduction to geothermal Energy. 18 overbearing, 2002. http//www.greenjobs.com/Public/info/industry_background.aspx?id=11Idaho National Engineering and environmental Laboratory.

An Overview The term geothermal comes from the Greek geo meaning earth and therine meaning heat thus geoth ermal energy is energy derived from the natural heat of the earth. The heat that flows from the Earths hot interior due to crustal plate movements, zones of high heat flow, may be located close to the surface where convective circulation plays a signifcant role in bringing the heat close to the surface (World Bank Group, 2004).earth coreThe Earths crust, on which we live and depend, is in large part the product of millions of once-active volcanoes and tremendous volumes of magma that did not erupt but instead cooled below the surface. Such persistent and widespread volcanism has resulted in many valuable natural resources throughout the world. ... Groundwater heated by large, still-hot magma bodies can be tapped for geothermal energy. -- Excerpt from Brantley, 1994, Volcanoes of the United States, USGS General Interest PublicationDeep circulation of groundwater along fracture zones will bring heat to shallower levels, collecting the heat flow from a broad area and concentrating it i nto shallow reservoirs or discharging as hot springs. These reservoirs may contain hot water and/or stream. By drilling into these reservoirs, the hot water and/or steam is piped to the surface where it is used for direct use applications, or the high pressure steam is separated to drive turbines for power generation. The low energy waste water form such power generaiton is then usually re-injected back into the reservoir, or further utilised for direct heat applications. This technology enables it to be utilised to generate electricity and provide domestic and industrial heat.
