It wouldn’t have to completely black out the entire country. Just 25% would be enough. What would be the outcome if SoCal were blacked out? What about the NE?
If 60 million people in a region suddenly lost ALL power, it would be catastrophic for the country. Most of the transformers that would be destroyed are made in China. What if they simply refused to sell them to us?
Imagine if the blackout in the NE in 03 had lasted for 6 months.
