It would be disastrous...Monstrous vanish. Our human progress can't proceed as it is without power. The greater part of the general population living in the urban and rural regions would come up short on sustenance in short request. They'd escape to the provincial territories. Most beyond words the way. The rustic zones rely upon power as much as the urban zones for sustenance, water, fuel, and so forth., yet would likewise capitulate. The principal winter in the US would realize the passings of presumably north of 200 million individuals. Before the finish of an entire year, my figure is that there'd be under 50 million individuals left. Likely less. 

Regardless of where you are, except if you're living in a power less lodge in the forested areas, your life relies upon electrical power. The US would stop to be a country state and would vanish. Hardly any individuals can "subsistence survive". For all intents and purposes no one knows creature cultivation or how to lash a little furrow to a bull. Less would know how to make one. 

This is valid for any country, with the exception of the most crude agrarian regions. The cease to exist would be something out of a dystopian motion picture. It would not be lovely no doubt.
