Growth in german wind capacity is slowing. Soo... then the plan is to keep on with lignite and gas? Am I missing something?

Again, I have not made any claim about seconds. I have nevertheless almost certainly misunderstood, and likely as a result of ignorance. I apologize; I've been to hasty. You're clearly well spoken on the topic, and I appreciate your sentiments. I found it a bit surprising that one of you primary claims was typically the only significant downside presented about renewable sources. In that way, I happen to think your stated value of 45 minute transition is still faster than we can make the wind blow harder.

However, with further thought I suppose if you have enough renewable generation equipment to generate 100% demanded loaded even at minimum natural capacity, then you would indeed have a much better response to demand. I hadn't thought of that before, but that is the dream and something for which we should strive.

I'm not actually sure the specific numbers for gen4 reactors, but I feel until none of the pie graph is fossil fuel, all research for improved generation methods is a worthy endeavor. I was a bit accusatory, but I don't think I'm alone there. I didn't mean to spread propaganda, and I don't think you have either. What I meant was strictly that the information seemed incorrect. I'm probably wrong; I often am.

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.

I’m no longer mixed up. I mistook your meaning. You’re just right. Thank you for clarifying and helping me understand.

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.
