Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth`s crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). The geothermal gradient, which is the difference in tempe....

Heat from the Earth's interior that is a potential source of energy. The commonest way of capturing the energy from geothermal sources is to tap into naturally occurring hydrothermal convection systems where cooler water seeps into the Earth's crust, is heated, and then rises to the surface.

Geothermal energy is energy extracted for heating and electricity generation from natural steam, hot water, or hot dry rocks in the Earth's crust. Water is pumped down through an injection well where it passes through joints in the hot rocks. It rises to the surface through a recovery well and may be converted to steam or run through a heat exchang...

Geothermal energy harnesses the heat from within the earth. Typically, the heat is used to create steam which spins a turbine and generates electricity. Geothermal heat pumps are used for home heating and cooling by using the ground temperature air to regulate the temperature in the house.
