The problem with non-nuclear green is that the big payoff is still pretty far away. So lots of investment is still needed. In this time, it can be justifiably criticized for not being THAT beneficial to the environment and being expensive. But that doesn't mean it should not be prioritized.
In my province, we recently moved away from coal plants, and that was attributed to our green energy push, but they reality is that coal used to account for 10ish percent, now it accounts for 0, and solar/wind used to account for 0.8 and now it's like 1.8. The difference was mostly made up on the back of nuclear. We need to spend more effort on making nuclear cheaper, I think, if we want best of both worlds here.
