Eventually perhaps we could get the power from fusion, or from solar power satellites (which get more sun then collectors on the ground even during the day in the dessert, and which are in the sun most of the time, not just half the day on clear days).

Fusion, we could only wish. Forty years ago when I was a physics major in college we thought we might solve the "fusion problem" by the 1990's. It didn't happen. It still isn't happening.

Maybe in a hundred years if we are lucky.

Have you checked out how much it costs to put one pound of something into orbit? Let alone a much, much higher orbit that would be required for space solar power? (not to mention the ongoing maintence costs for such a system in space)

Nope.

It will all be done with solar power on the ground in the long run.
