Geothermal Energy Essays -- Science Energy Chemistry Essays

Geothermal EnergyGeothermal susceptibility is a superior source of skill because it is constantly being produced. Radioactive decay of nuclei with long fractional lives that were imbedded in the grounds interior during its genesis accounts for seventy percent of the globes internal energy. The remainder of this energy is derived from either the residual heating left over form the Earths formation, gravitational forces, or meteorite impacts.Geothermal energy is available anywhere on the planet. On average the Earth emits one sixteenth of a watt per meter squared, however this number can dramatically increase in regions near volcanoes, hot springs and fumaroles. Therefore, the uniqueness of from each one location around the world causes the Earths internal heat to be stored subway in many different natural structures. In both(prenominal) areas, the globes heat is stored in the rocks that form the Earth. There is a normal temperature increase, called the Normal Geothermal Gradient, of 30 degrees Celsius for every kilometer dug beneath the Earths surface. However, the precise amount of temperature increase that occurs as ones depth increases is not a constant over the entire surface, it depends on the rocks temperature. Therefore, in hotter sections of the planet there is Hot Dry Rock which produces an increase in temperature of forty degrees for every kilometer dug below the surface. In addition, a reserve of geothermic heat even hotter than the solid rock type is molten magma, which is melted rock. Also, some regions of the planet house underground aquifers that use water to store large quantities of heat. Some areas contain vast hot water pools deep below the surface called Hot Water Reservoirs. In other places the conditions are r... ...ability it will surely be developed much more extensively in the near future. This source of energy will in like manner be able to be used for a long time into the future because geothermal energys sour ces will continue to replace the energy used. In addition, it is estimated that the Earth can produce 600,000 exajoules of energy over five million years. This rate is believed to be enough energy to fulfill human energy requirements for the rest of the biosphere.
