My understanding is that all electrical grids would be fried. Sci-fi has a little “love affair” with this scenario, there have been many stories with total grid wipeout as a starting point. Whatever the reality would be it would be brutal. We depend on electricity in some form for most of our daily lives.
There was an equipment failure the other day here in Hale, the town was out of electricity for approximately an hour and a half, whatta mess. It wasn’t even a destructive failure, cell tower went down, no internet, stores couldn’t ring up anything, gas pumps didn’t work. Thank god we only have the one stop light and traffic was still slightly hazardous at the intersection.
90 minutes to make you realize how fragile it all is.
