There’s a limit on how much we can practically get from solar,

Most residential buildings can self sustain from solar. Dense cities not, but there is dual use grazing and agriculture land, and small portions of desert that could power the world. Solar is enough for type 1 civilization. Nuclear plant energy density is overstated due to their + uranium mine exclusion zones, which could produce more solar power than the uranium content available in those mines.

Wut? Maybe on the equator, but while I can easily meet my yearly power consumption with solar panels (In fact, I net supply about 1100kWh), during this lovely winter day they generated a whopping 0.3kWh.

We're not discussing nuclear here, we're discussing fusion :)
