Thanks, this was informative. It wasn't clear to me, but I think the study does not account for switching heating from burning NG in the dwelling to electricity

Thanks, this was informative. It wasn't clear to me, but I think the study does not account for switching heating from burning NG in the dwelling to electricity. I don't have numbers, but I'm pretty sure that's going to introduce an enormous load on the system, and is my main source of skepticism for wind/solar/storage as a solution for all electricity generation in places like Minnesota.
