The main problem is that nobody is building new power except China. In space solar panels are 5x more efficient and run 24/7 and you don't need the kind of permits you need to build on earth. That, and you've got NGOs funded by China connected billionaires that relentlessly sue to stop data centers and new power in the United States, and you don't have to deal with that B.S in space because it's federally regulated and there isn't any environmental impact to sue over.
