No reason for people to splinter the effort on clean reliable power.
If we only go after solar, wind and storage -- how are we ever going to get to long form space travel and continue to level up our technology for energy? How will we get to fusion?
By researching fusion? Imagine how much research you could do with all the money that you didn't waste on building uneconomical nuclear power plants
Nope. One of the fundamental premises of money is that it circulates. The only way money could not be re-spent is if the money supply were to decrease.
The total volume of new power generation is going to be mostly determined by how much those capital holders value it. If there's more utility in power this year than last, we may see more new starts in generation projects, regardless of which type of generation those projects are doing.
