France derives 71% of its electricity from nuclear energy. In the US it's around 20%. So while nuclear power can't replace everything, even with current technology they could power the great majority of electricity generation. Sure we can't simply build them everywhere. But the main barriers to building enough of them to make a big difference aren't technical.
