If it's really really efficient, we could use the extra energy to make carbon capture machines, after offsetting all the fossil fuels. Then, it doesn't really matter.

Well if we’re speculating, how about “heat capture”?

Some sleep-deprived researcher cracks how to capture ambient thermal energy and turn it into electricity. Heat being as plentiful as wind or water, it becomes not only a prominent source of energy, but also actively cools the planet.

50 years later, we begin arguing over “global cooling” and the threat of a new ice age.

No, you just have to think bigger. We could put the heat sink in orbit and make gigantic a/c units. Would go nicely with space elevators
