Answer:
geothermal energy
Step-by-step explanation:
Geothermal energy is a renewable resource. It is a form of energy that is derived from the heat generated within the Earth's core. This energy can be used for heating and cooling buildings, generating electricity, and other industrial applications. Unlike fossil fuels and nuclear energy, geothermal energy is sustainable and can be replenished over time. It does not rely on the combustion of fossil fuels or the splitting of atoms to generate energy, and it does not produce greenhouse gases or other harmful pollutants.
