The best time to ignore the nuke shills and build wind and solar was the 1940s when both wind and solar thermal were proven economically and fission hadn't happened yet.
I disagree... the biggest "issue" I have with "renewables" is the storage problem.. That 20 years gives you time to figure out something while reducing the carbon output
..no it won't because the new nuclear will generate nothing for 20 years. Whereas the renewables will reduce some carbon, even if we pretend that storage is both unsolvable (as opposed to already cheaper than nuclear) and necessary in a grid that's already 40% hydro.
