Geothermal Energy A General Overview with Specific Reference to the Long Valley Caldera IntroductionGeothermal energy is a attend that uses heated ground weewee to turn turbines that produce electricity. The water is warmed by the earths natural heat. Geothermal energy was first developed by Count Lardarel of Lardarello, Tuscany in 1827 (Geothermal.marin). Since wherefore many other countries have developed geothermal technology, yet it is a resource that remains mostly untapped. As the need to find alternative burn sources grows, geothermal energy becomes an interesting option for potential future energy production.Geothermal energy production involves a complex set of issues. First it is meaning(a) to place geothermal energy in context of todays energy needs. Currently, one of the ongoing dilemmas of energy use is the worldwide allocation of resources and general rate of consumption. at bottom this essay, I will illustrate a brief history of energy use and development. Ge othermal energy can only be produced in feature geological settings. Only compasss with recent volcanic activity can produce the heat needed for geothermal production. Therefore, a basic understanding of tectonic surface movement and volcanology is required to understand the production of geothermal energy. I intend to give a general background on the geological settings infallible for the production of geothermal energy production. Lastly, I will center on one region in particular, namely the Long Valley Caldera in California. This is an area that is saturated with historical and present volcanic activity. The recent volcanic activity makes it an area that is perfect for geothermal energy production. I will discuss in particular the Mammoth Pacific plant that operates in Mammoth Lakes. What is Geothermal Energy?The production of geothermal energy is a way of utilizing heat that is created by volcanic activity to produce electricity. Within a geothermal system, grou nd water is heated by magma chambers to temperatures as high as 450 degrees Fahrenheit. However, the temperature of the water depends on the geothermal gradient. A gradient signifies how deep below the surface the heated water is. The deeper down the water is in the earth, the hotter it will be (this is called a steep geothermal gradient). The water either reaches the surface of the earth naturally in the form of geysers, fumaroles, or hot springs or it must be drilled.
