What is geothermal energy used for?
Geothermal energy comes from the heat of the Earth's depths. About 30 kilometers below the surface is a layer known as the earth's mantle. This is the source of the gas and lava that erupts from volcanoes. Springs and geysers, with temperatures above 250 degrees Celsius, are also heated by the mantle.
Because of its high temperature, the mantle is a promising source of energy, especially in areas where hot water is very close to the surface.
Iceland, a country that has a large number of volcanoes and springs, makes efficient use of this energy resource, about 85% of houses use it.
