You are very defintly confused here,;) or there, in Pakistan where some of the rulling class will brag about never getting utility bills, but the reality is that every built thing, down to the roads is there for them, but at root the main concepts of fuedal societies are intact, and going solar, fits in quite well, as it can be set up as distributed systems that will literaly conect into a larger grid, based on alliegences. The adoption of electric cars and especialy trucks/tractors/farm/industrial will follow quickly and allow fossil fuels to be reserved for strategic use. The real kicker will be batteries that have decadal life spans allowing for predictable, "one time" infrastructure investments that can the become self supporting through use "fees"
