So,geothermal energy is heat from within the earth. We can use the steam and hot waterproduced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat iscontinuously produced inside the earth.ENERGY INSIDE THE EARTH Geothermal energy is generated in the earth's core, about4,000 miles below the surface.eothermal energy is a renewable energy source because the water is replenished by rainfall and the heat iscontinuously produced inside the earth.
