Fission works fine, although admittedly it's getting bogged down by
regulations and its reputation has suffered from some extensively
publicized accidents. Nuclear hasn't caused even close to as many
fatalities as has coal. France runs on nuclear power and it's doing
fine.

It's fusion that has failed to live up to its promises.

Renewables can be made to work, but need to learn to play well in
the existing infrastructure and need some kind of backup which
makes it more expensive.
