I can't imagine how I and hundreds of millions of others can heat their homes during cold nights without fossils or a 30cm thick XPS insulation, about which hardly anyone talks about. I have solar on the roof and batteries and they are totally dead for 2.5 months in a row in a sunny country. How can millions of car batteries be managed efficiently without heavy environmental damage? EVs don't scale for all even with serious infra (recycling, on spot change, fast chargers). The only viable solution is to continue burning and burning, if we don't want to severely degrade our quality of life: now fossils, a little woodchips like Sweden and in the end biofuels, synthetic fuels and hydrogen. And let anyone use nuclear at their own taste. Solar/batteries cannot extend beyond a small window and wind is not reliable.
