There is probably a natural nuclear reactor in the Earth’s core. Think when the earth was formed, heaviest elements like Uranium would naturally concentrate at the core. Therefore Geothermal is potentially an unlimited resource, at least until the reactor runs out of fuel, but I would guess thats millions if not billions of years away.
