I still maintain that the days of a central grid for rural areas are over. I am following closely the vehicle to home technologies that are being marketed. Right now they are catering to rich fear filled people driving trucks and wanting to keep their central ac going during a hurricane blackout. A shitty use for the tech but That is not the tech's fault. There is no reason why your house could not have a small battery bank and your car the large battery bank. The large solar array could do the house and the extra going to your car. The car could trickle back to the small house battery as needed at night. All of that is off the shelf and can pay for itself slowly over time. Upfront costs are large but they are the real costs not invisible ones. What bugs me is we have gotten used to buried costs that you don't see but are real. Cost like tens of thousands of miles of copper wires, transformers, substations, land devoted to power lines, tree trimming, coal subsidies, gas subsidies, clean up costs, to name but a few. All of the electrification tech can work as long as we change our narrative of big being better. I'm not too hopeful on that one. That's the version of the future I choose to plant my flag on these days.
