If the world's energy usage increases by 2% for a thousand years we use 3.4 * 10^4 times more power than the solar radiation reaching the earth (1.02^1000 * 15/170000). Enough power to boil off the oceans in about a day (if I can believe Reddit and my math isn't off)

Yeah, I've done the calculations for 3% at 2%. I didn't feel like doing them again, so just went with a conservative bet.
