I have made this point forever, but it always bears repeating -- the variability of wind and solar require hot fossil fuel backups that leads to little reduction in total fossil fuel generation capacity (so that wind and solar investments are entirely duplicative) and less-than-expected reductions in actual emissions.
I don't think wind will ever be viable, except perhaps in a few unique offshore locations. Solar is potentially viable with a 10x or so reduction in panel costs and a 10-100x reduction in battery/energy storage costs. I honestly think that day will come, but we are not there.
From the Unbroken Window comes this slide from an interesting presentation at the Ontario Society of Professional Engineers, essentially making the same points I and others have been trying to make for years.
I made the point about nuclear in my climate legislative proposal here.
