Geothermal Energy, hope this helps.

Answer 2

GEOTHERMAL ENERGY. This form of energy is not generated by the Sun. It is made by the nuclear reactions taking place all the time deep inside the Earth. These make heat energy in the Earth's core, and the heat moves around inside the Earth by convection. ( i think correct me if i'm wrong. )
