b) Solar Power (and wind) won't replace all power on Earth. It can't,
not from orbit and not from the ground. But solar can take a large
part of the load during the day and let traditional power (oil,
natural gas, etc.) handle the night and periods of calm winds.

Space based power can supplement base load. Ground based solar can't.

Huh? Ground based solar already is, a tiny fraction of course, but it
already is supplementing.
