There is the slight issue that no matter what energy source we use, we need to reduce energy growth. Postulating a meagre 2.3% growth in energy use forever, we'll get the surface temperature of Earth to the boiling point of water in 450 years.

- kragen 15y agoYou can refrigerate the Earth. You don't even have to refrigerate it; approximately the entire sky except for the Sun is a few degrees above absolute zero, so you just have to increase your radiative coupling to it --- effectively putting cooling fins on the Earth. Or you could use the energy somewhere besides on Earth.
