Who sold Congress this pile of manure?
Total grid shutdown MIGHT cause 2 to 3 percent of population (medical patients) to croak pretty quick.
Any of the other dead would pretty much be due to stupidity and dependency.
Just imagine that your pc is the same one in food distribution points - those gigantic warehouses - and they both get fried at the same time as the motors on the forklifts - on the third day, what’ja gonna eat?
And if you have some food, will it last the years it will take to restore the grid? If it does, how many others will those stores feed besides you and yours?
