The scale of chemical batteries needed to handle a deeply decarbonized grid is almost unfathomable. It is certainly physically possible (i.e. not forbidden by the laws of physics), but to postulate that it will go off without significant hitches related to environmental concerns, resource issues, transmission permitting issues, land-use issues, chemical disposal/recycling issues, energy return on investment shortages, etc. seems really optimistic to me. I get that this is what people want to happen but I just think it's vastly harder than most people think. > Enough sunlight falls on Earth in an hour to power humanity for a year. There's enough recoverable fission fuel on Earth to power humanity for a billion years. Energy resources is not the issue. Accessing it economically and in politically-compatible ways is.
