Geothermal energy 2

I. Overview of Geothermal Energy Geothermal energy (from the Greek haggling geo [earth] and therme [heat], thus earth heat energy) is a domestic energy re blood line with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). gamey pants is brought up to near the break through by thermal conduction (diagram: B) and magma. This heat heats ground peeing to form hydrothermal resources (naturally occurring hot water/steam in fissures [diagram: C/D]). Wells (diagram: F) are drill to tap fissures for hot water, and the steam can be employ to generate electricity, as described in the next section. acid water may also emerge on the surface as hot springs or geysers (diagram: E). Utilizing geothermal energy not lonesome(prenominal) contributes to our energy supply, but also reduces energy consider (through the use of geothermal pumps to heat and cool buildings, reducing the extremity for natural gas and other nonrenewable resources). It is unfortunate that only a small part of our geothermal resources are organism apply today.

Hot water, at temperatures between 300 and 700 degrees Fahrenheit, is brought from an pipe reservoir to the surface and is converted to steam by utilise changes in pressure.



The steam and liquid are separated, with the steam turn turbines (generating electricity) and the water is injected back into the reservoir to maintain the chambers pressure.

Sometimes the hot water is used directly for home, and sometimes greenhouse, heating. It is also used to speed up the growth of aquatic animals (aquaculture).

II. Dependency on Geothermal Energy Although we (the United States) are not pickings advantage of all of the geothermal sources in the United States, the source is here today; it is not merely a intrust for the future. The production of geothermal...
