The distributed cost of $23k for 130 million people is definitely less costly than the 7,300 power plants, nearly 160,000 miles of high-voltage power lines, and millions of miles of low-voltage power lines and distribution transformers for usage and cost, shipping of fuels and piping of gas. We just take that for granted because it's already here. THAT cost has already been paid but also continues to be paid for every year. The solution will present itself at this price for only so long before the fragility of the US electric grid shows itself. Then there will be a rush on energy because everyone is squabbling over which "One-size-fits-all" solution should be the main point of centralization. Coal and gas, so called "Renewables," or Nuclear. They all share the same problem a centralized point of failiure. I am not saying sovereignty is easy, I am saying it is necessary.
