We get 174400 TW from the Sun (1367W/m2 over the Earth cross-section, which pretty much balances out with the outgoing blackbody radiation at something like 5 deg C IIRC. This would be the surface temperature if there was no internal heating. This slows down cooling of the mantle because there's no cold reservoir for it to cool into. |
