I feel sad when I see replies like yours, because honestly I don't think you understood my point at all. If you combine all the other things you mention here, all of them together, right now, are incapable of addressing even 1% of our energy use, let alone be the backbone of a grid to manage intermittence. The cost analysis you describe is imaginary, because again, those technologies simply don't exist at scale. There is not a single country in the world that operates with any of your strategies, but most developed economies regularly use nuclear in their mix. We could address climate change with nuclear today, or we could wait until these technologies are mature and cheap, which may come too late.
