You think electricity is not made with CO2 ? no country is 100 percent nuclear or solar and batteries are not made using a clean process either. There is absolutely no free lunch and pretending thIngs are easy is ignorant at best.

I said converting the grid to battery-backed solar. Batteries are clean. Cobalt is a heavy metal but when mined sustainably and built with renewable energy the pollution from a producing a battery is very little.

There are plenty of countries whose power is 100% or close to it "made without CO2", usually with help from hydroelectric (e.g. Norway). Solar panels are becoming cheaper and cheaper and cheaper. The situation is closer to free lunch than you imply!
