That seems terribly low, but apparently it's correct (humans need right now about 18TW). This means a lot of Earth's heat is actually coming from the sun itself

That seems terribly low, but apparently it's correct (humans need right now about 18TW). This means a lot of Earth's heat is actually coming from the sun itself.
One small nuance: the OP asked about the heat generated by Earth's mass. The 47TW is split between the original heat from the formation of the Earth and the nuclear decay of radioactive elements.
