Nuclear power plants are the only real solution to keep the world generating enough power, if they want to eliminate fossil fuels.
I agree and believe this is the one we need:
Bill Gates, Warren Buffett building nuclear reactor in nation's biggest coal-producing state
I think you are right, or the smarter ones will go Amish. But I think rather than build one or two large plants which are hard or impossible to control if they have issues, many smaller ones that would each be much easier to control if there was an issue would be the wisest way to do it. Divide and reduce the risk, and if one goes down the other nine are still up and running and there is no disruption of service.
