Introduction to geothermal energy Pan Guangde (mechanical engineering college, liaoning fuxin of liaoning engineering technology university, 123000) 【abstract ] geothermal energy is renewable energy，have clean no pollution, can use the characteristics of high value. Geology on the geothermal resource is divided into five categories: steam, hot water operated，hot dry rock type, pressure type, magmatic type. Are widely distributed. 【key words 】geothermal energy, characteristics, types，distribution，geothermal energy utilization，the model state Geothermal resources is a very valuable mineral resources，a comprehensive its function，more widely used，not only is a kind of clean energy resources，available for power generation，heating，farming，etc， but also a kind of available for extracting bromine，iodine, sodium borate，potassium, ammonium salt， etc. Industrial raw materials of hot brine resources and natural water resources, is also a kind of precious medical thermal mineral water and reference mineral water，and water The characteristics of geothermal energy On earth structure, the majority of the Midwest in the Eurasian plate inside the crust uplift area and crustal subsidence area, respectively form bulge fracture type and sedimentation basin inside the version type of low temperature geothermal resources. Western yunnan and western sichuan，southern Tibet is located in the Eurasian plate and Indian plate collision boundary，on plate margin magmatic activity type high temperature geothermal resources is extremely advantageous. In the tectonic environment，formed the Midwest with different temperature，degree of mineralization and special chemical components of geothermal resources. Both steam and low temperature in the underground hot water resources, and the underground light hot，hot brine and high mineralization thermal mineral water. This provides necessary conditions for effective use of geothermal resources. Hot spring resources. Hot spring the warm water at 25 degrees Ce
