Geothermal Energy: A Clean and Renewable Energy :: Alternative Energy Sources

What is Geothermal Energy? The term geothermic comes from the Greek geo meaning earth and therine meaning change thus geothermic energy is energy derived from the natural broad(prenominal) temperature of the earth. The heat that adverts from the Earths importunate upcountry due to crustal plate movements, zones of gamy heat advert, may be find close to the surface where convective circulation plays a signifcant role in bringing the heat close to the surface (World Bank Group, 2012).The Earths crust, on which we live and depend, is in bombastic part the product of millions of once-active volcanoes and tremendous volumes of magma that did not erupt but sooner cooled below the surface. Such persistent and widespread volcanism has resulted in many important natural resources throughout the world. ... Groundwater heated by immense, still- glowing magma bodies can be tapped for geothermic energy. -- Excerpt from Brantley, 2014, 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 into shallow reservoirs or discharging as hot springs. These reservoirs may contain hot water and/or stream. By cut into these reservoirs, the hot water and/or steam is piped to the surface where it is used for enjoin use applications, or the laid-back school pressure steam is separated to find turbines for precedent generation. The low energy waste water form much(prenominal) federal agency generaiton is then usually re-injected back into the reservoir, or further use for bring heat applications. This technology enables it to be employ to generate electrical energy and provide domestic and industrial heat. Geothermal energy has proven to be reliable, economic, environmentally friendly and renewable (World Bank Group, 2012).In general in that respect are two main categories, (1) the high temperature resources and (2) the moderate/low temperature resources. The high temperature geothermal resources - 220 degrees Celsius and up - are predominantly found in volcanic regions and island chains. The moderate to low temperature resources are found on all continents. The high temperature are almost always used for power production patch most of the low temperature resources are used for direct heating purposes or agriculture and aquaculture. How does Harnessing Geothermal Energy Work?Deep wells, a ml or more deep, can tap reservoirs of steam or real hot water that can be used to film turbines which power electrical energy generators. There are 3 types of geothermal power plants in use today, and they areGeothermal Energy A Clean and renewable Energy Alternative Energy SourcesWhat is Geothermal Energy? The term geothermal comes from the Greek geo meaning earth and therine meaning heat thus geothermal energy is energy derived from the natural heat of the earth. The heat that flo ws from the Earths hot national due to crustal plate movements, zones of high heat flow, may be situated close to the surface where convective circulation plays a signifcant role in bringing the heat close to the surface (World Bank Group, 2012).The 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 precious natural resources throughout the world. ... Groundwater heated by large, still-hot magma bodies can be tapped for geothermal energy. -- Excerpt from Brantley, 2014, 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 into shallow reservoirs or discharging as hot springs. These reservoirs may contain hot wa ter and/or stream. By drill 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(prenominal) power generaiton is then usually re-injected back into the reservoir, or further utilised for direct heat applications.
