Nuclear is not option. It's very expensive, slow to plan, build and operate, quite dangerous in operation and waste it creates and political risky, now that russia has a major control of nuclear fuel. Fusion is not even usable in the near future. And even the benefits are not good enough to justify all those problems. There is no single solution for our problem. We need a dozen of them to reshape the world, and at no phase has nuclear a place, because it will always take to long and too much money.
