Which type of energy incorporates earth’s thermal energy?

Geothermal energy specifically harnesses the heat that comes from the Earth's interior. This thermal energy originates from the natural decay of radioactive materials and the residual heat from the planet's formation. By using this heat, geothermal energy systems convert thermal energy into electricity or direct heating applications, such as heating buildings or greenhouses.

Wind energy, on the other hand, captures kinetic energy from moving air, while solar energy derives its power from sunlight and nuclear energy comes from atomic reactions, typically involving the fission of heavy elements. None of these options utilize the Earth's thermal energy in the way that geothermal energy does, which is why geothermal is the unique choice in the context of incorporating Earth's heat into energy production.
