Not only that, but as terrorism looms, making the system more resilient is a plus. If homes were all self-sustaining, it would be impossible to black out major regions.
Big business will probably always need to be tied to the grid, but at least homes would be better off.
Absolutely, retain that independence. Hook up to electricity to fulfill the zoning crap, but keep it off...and pay that tiny bill of minimum use. It might come in handy on occasion.
Tiny homes adapt to that very well....easily built, heated and add extra insulation.
