I cannot wait for nuclear fusion to finally be here so people will stop worrying about the electricity consumption, and high consumption will not mean pollution or whatever.
All the electricity we generate becomes waste heat in the atmoshpere. Global energy use is currently ~0.1% of Sun power hitting the Earth. USA uses ~10x more electricity per person than India does, assume bringing everyone up to USA levels means we'll be around 1% of Sun power. Grow the population from ~8Bn to predicted ~12Bn and we'll be around 1.5%.
And then everyone gets "too cheap to meter" fusion power? There is not a /lot/ of headroom there, we surely can't go to outputting as much waste heat again as the planet gets from The Sun - and before you say "solar", you already said "fusion".
Energy usage will explode! Imagine all the ways to use energy that hasn't been economically viable before. I think the only way that will work out, is if the energy consumption happens off-planet.
