The idea that climate activists don't focus on energy production seems kind of detached from reality. Climate activism has pushed heavily on renewable energy. They're not advocating for nuclear, but that makes sense at the moment even if you're very bullish on nuclear — pushing for more nuclear power will result in no reduction in emissions for over a decade, and we need to come down a lot before then. Nuclear is possibly a viable long-term strategy, but in order to get to the long term, we need to move to renewables in the short term.
