Does Nuclear count as Green Energy? I feel like it should, since it doesn't really pollute and lasts a lot.

Fusion has basically nothing to do with climate change. Even if Fusion were cracked tomorrow, the scale out would be such that you couldn't meaningfully supply a lot of base load power before you'd need to be net neutral. My take is that fusion, when available, alongside solar, would be used for carbon dioxide removal.

Technically the same goes for fission, as new reactors take well over a decade to build nowadays, which is too late for our climate goals and typically diverts resources away from renewables.

Yeah good point. The numbers are a bit closer for fission though. Like phase one we can do renewables but electrification needs way more power than available currently. E.g. green hydrogen. There are valid scale up scenarios where fission is part of the picture, but almost none of them make sense under capitalism.
