(Geothermal Energy))consists of the crust extract natural thermal Energy, this Energy lava from the earth's interior, and exists in the form of heat, is caused by volcanic eruptions and earthquakes of Energy. The interior of the earth temperature of 7000 °C, and in 80 to 100 GongYing depth, the temperature will drop to 650-1200 °C. Through groundwater flow and the lava from the ground into the 1 to 5 km of the earth's crust, heat can be transferred to a place close to the ground. Hot lava nearby groundwater heating, the heating the water will eventually seep the ground. Using geothermal energy, the simplest and the most appropriate cost-benefit method, is to directly access the heat source, and extract its energy. Heat (thermal energy) is also called heat, energy, etc., it is the energy of life. People's labor service activities, sports, learning in class every day and in all other activities, as well as the human body to maintain normal body temperature, various physiological activities consumes energy, like steam engine need coal, the internal combustion engine with gasoline, motor need electricity. Human long ago began to use geothermal energy, such as use of hot spring bathing, medical treatment, use of underground hot water heating, build greenhouse crops, aquaculture and drying of grain, etc. But the real understanding the development and utilization of geothermal resources and large-scale began in the middle of the 20th century. Most geothermal energy is renewable energy, from the depths of the earth it up in the earth's molten magma and the decay of radioactive substances. There is a small part of the energy from the sun, about 5% of the total geothermal energy, on the surface of most geothermal energy from the sun. Deep groundwater circulation and the magma intrusion to the earth's crust, far from the heat from the depths of the earth to near surface layer. Its reserves a lot more than the amount of people by using energy and most concentrated on the edge of the tectonic plate area, the area is also volcanoes and earthquakes. It is not only non-pollution clean energy, but if you don't exceed the speed limit of supplementary heat extraction rate, then the heat energy and renewable. How to take advantage of the huge potential energy? Italian leather is ROM, auspicious nony, prince kang's for the first time in 1904 Mr Rudd ray luo natural geothermal steam to generate electricity. Geothermal power generation is to use hydraulic or pumping water into rock blasting fragmentation method, to produce high temperature steam, then take out the ground drive turbines make a electric energy by generators. Part in this process, will not used to the water vapor
