Unfortunately renewables won't quite get us there, because many of them have seasonal outputs and we don't have any good ways of storing energy on a large scale. Wind, solar etc. can't produce energy 24/7, and when there's overproduction we can't store it anywhere. There's some interesting solutions like this Finnish company working on a sand battery but nothing that's good to go right now.

Right now nuclear energy is the only good solution. I'd bet on small-scale modular reactors, at least if we can collectively get over the irrational fears many have about anything nuclear.
