On the other hand, if we are lucky and we go to covid-19 zero in a year everyone will be happy, but if we go to fossil fuel zero in a year everyone will complain that the electricity bill doubled.

Around this time the world's wood will be exhausted, and only the middle latitudes will be habitable.
No mining will take place. No chemicals for purification. No new green energy. No new batteries.
Etc etc. Etc.
