Geothermal energy sources found in the world.Geothermal in the world divided into major characteristics. 3 features:1. where is most of the water vapour (Steam Dominated) as a heat source for the catchment consists of more than 95% of the water vapor in General is often the source is closely related to the hot lava of hot steam temperature tuen is higher than 240 degrees Celsius or above. The sources are mainly water vapor is found very little in the world;But it can be used as much electricity as The Geyser Field in the State, California. Country United States and Italy in Larderello, etc.2. where is the most hot water (Hot Water Dominated) as the source of the catchment consists of thermal collectors. Hot water hot water temperature as most are from 100° c or higher. This system is most common in the world, such as the Cerro Prieto in Japan and Mexico in Hatchobaru, etc.3. dry hot rock sources (Hot Dry Rock) is a sedimentary rock which is heat, texture, but no hot water or steam flow, circulates, so if it is necessary to adopt a soft cold water down toward the hole drilling, water gets hot from hot rocks by flowing. Turnover within the cracks that are done. Then this summer, pumping up one hole and another hole drilling, drilling down to cut the stone to crack the source of dry heat. The trial is the California State electricity. Country Oita Prefecture of Japan, and the United States.
