Geothermal heat is hot enough to melt rock beneath the crust of the Earth, creating magma. Most of the magma remains below and, like a built-in boiler, heats up all the surrounding rocks. When underground water comes into contact with this heat it also gets very hot, sometimes to temperatures of ۳۷۰؛C.At certain places worldwide, especially at margins of continental plates and other places called ‘Hot Spots’, the heat is shallow enough that it can be accessed and used by man to product Electricity or direct using.The true using of geothermal energy dates back to more than ۱۰۰ years ago . Noticing the thermal , geothermal systems may be divided into different kinds that can be tapped with certain methods.Geothermal energy is a sustainable ¸ low costs¸ free fuel and low pollution . Hopefully, geothermal energy will play its role in a more sustainable energy strategy for human-kind, reducing or eliminating the use of polluting fossil fuels.
