Geothermal Energy Essays -- Science Energy Chemistry Essays

geothermal EnergyGeothermal cypher is a superior source of strength because it is constantly being establishd. Radioactive decay of nuclei with long half lives that were imbedded in the Earths interior during its genesis accounts for seventy percent of the humankinds internal energy. The remainder of this energy is derived from either the residual estrus left over form the Earths formation, gravitational forces, or meteorite impacts.Geothermal energy is available anywhere on the planet. On fair(a) the Earth emits one sixteenth of a watt per meter squared, up to now this number can dramatically amplification in regions near volcanoes, wild springs and fumaroles. Therefore, the uniqueness of each location around the world causes the Earths internal heat to be stored tubing in many polar natural structures. In some areas, the globes heat is stored in the joggles that form the Earth. There is a normal temperature increase, called the Normal Geothermal Gradient, of 30 de grees Celsius for every kilometer dug below the Earths surface. However, the finespun amount of temperature increase that occurs as ones depth increases is non 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 geothermal 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 Brobdingnagian hot water pools deep below the surface called Hot water supply Reservoirs. In other places the conditions are r... ...ability it lead surely be true much more extensively in the near future. This source of energy will also be able to be use for a long time into the future because geothermal energys sources will continu e 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 full energy to fulfill human energy requirements for the rest of the biosphere.
