It is a valid question, but to put it in perspective, the sun bathes us in dramatically more kWh than we need to annually power the world every few minutes. So fusion would be a drop in the bucket at a global scale.
- adrian_b 4y agoIn the beginning, of course. Nevertheless, the heating of the Earth puts a limit on the total usable nuclear power on Earth, both fission and fusion, it cannot be "infinite", but it must remain forever a small fraction of the power of the incoming Solar radiation, otherwise it would cause an excessive heating of the Earth by itself.

Being so wildly successful that our industrial heat rivals that of the incident energy of the sun would be incredible. No problems humans have ever faced would be in living memory (including mortality). This is a science fiction future that does not need planning from the minds of today. It would also have many solutions related to adjusting albedo.
