Pipes Control In A Geothermal Energy Plant Near Dieng Plateau, Central Java, Indonesia. Stock Image

Geothermal energy is the thermal energy in the Earth`s crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. The high temperature and pressure in Earth`s interior cause some rock to melt and solid mantle to behave plastically, resulting in parts of the mantle convecting upward since it is lighter than the surrounding rock and temperatures at the core–mantle boundary can reach over 4000 °C 7200 °F.
