Talk is cheap. They are doing nothing to “harden” the power grid.
It won’t matter much if the generation, transmission and distribution systems are hardened when every single end-device is fried. Except for my huge cache of incandescent light bulbs, that is. If they harden the power system, you’ll be able to find me in the well lit house.
I just finished reading “One Second After,” a book about an EMP attack against the U.S. It was not a pretty sight...food, clean water, pharmaceuticals all gone in a few short months. Mass disease epidemics and starvation. Mad Max bands roaming and destroying cities. Zero communications. Very few people with the skills to restore old pre-electronics machinery. Ammunition running out after a year. Game wiped out in the forests. People fleeing crumbling cities for the country side where they think they’ll find food. Harvests and stock rotting and dying because there is no transportation to bring them to market.
It is a shocking book, but it all seems quite plausible. The real threat is N. Korea or Iran launching nukes to 200 miles from freighters, probably much less so from solar flare-induced Compton Events.
