Also, happy to continue to peruse nuclear research and development, I agree that it’s worthwhile to try to improve the technology and to hope for breakthroughs in the field, I’m hopeful that nuclear fusion break-even and beyond can be achieved in my lifetime. But we need to take drastic action now to reduce fossil fuels and that means investing heavily in renewables asap.

I appreciate the apology but you’re still getting mixed up - I think we have a differing definitions of the word “responsive to demand”. You seem to have taken it as meaning, “we can scale up power generation when demand increases, and it’s dispatchable” which wasn’t what I meant - although I probably added to the confusion by improperly using the words “flexible”. I know that wind and solar PV aren’t dispatchable - solar thermal can be, same for solar electrochemical, but those are a bit oddball. For dispatchability, pumped storage really needs to be brought in to the picture, though I think hydrogen should be used much more for transport.

All I meant was that wind turbines are better at reducing electrical output and managing power grid frequency response than nuclear is, not that a given wind turbine is better at producing electricity at any given moment that we need more of it. I think that with scale and distributed power grids, the disadvantage of the variability of renewables becomes less of an issue anyways, but yeah, with all of the options available, there’s really no reason at the moment to increase the installed base of commercial nuclear power plants, and that’s all I really care about - reducing co2eq emissions as quickly and cheaply as possible. Whichever technology achieves that has my full throated support.
