being realistic given the current administration, the best avenue for those that care about climate change would be to lobby their representatives for nuclear and specially coal to nuclear transitions (https://www.energy.gov/ne/coal-nuclear-transitions) and lobby for more government funding directed to accelerate this. This would be palatable to the current administration while also supporting the goal of less c02 and other emissions.

Heck this also takes away any incentive to restart the coal plants by private companies if they are being financially supported and already in the process of converting them to nuclear, and it takes away an incentive to build more long-term because each nuclear plant provides a lot more power on average. Another thing to lobby for would be for more SMRs funding and less regulation overall in nuclear (it's insane how overly regulated nuclear is based on one soviet fuck up of a crappy underfunded/flawed powerplant (chernobyl). Fukushima plants (commissioned in 1971!) were hit with a once in a lifetime 9.5 magnitude earthquake and tsunami on top despite being less than 100 miles from the epicenter even with regulatory lapses and no direct deaths.
