Then there is the issue of power production:
We will *never* power our economy with windmills and solar panels. Ever. They are supplementary and not reliable. When wind power becomes a significant source of electricity, one storm or one calm spell is enough to black out the grid. And don't give me "but BATTERIES" or "but IMPROVEMENTS"... yes... this is true. Still doesn't matter. We need a non-carbon based base energy source that isn't dependent on the weather.
The only actual solution is to drastically reduce energy consumption in all industries, all parts of life, all countries. But this is politically toxic and will never happen. I've become resigned to the likelihood of collapse.
