Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn't a thing of the future, either.
Renewable. One of the foremost advantages of geothermal energy is that is it renewable and literally inexhaustible. Unlike conventional energy sources such as fossil fuels and nuclear, geothermal energy is a renewable energy resource like wind, solar, and wave energy. The heat from the earth is practically unlimited.
