If you are replacing fossil fuels with solar it will cause an incremental cooling because… Waste heat generated from electricity use is independent of the generating source. So replacing fossil fuels with solar power doesn’t change the amount of waste heat from electricity usage. But solar does produce an incremental cooling effect at the solar farm because photons - which would have otherwise produced heat - was converted into electricity instead.If I convert solar radiation into electricity, can I still heat the planet with it?
