The question is, how much would it cost to supply, say, Owen's number (30.3 kwh/day average household usage), using non-grid sources? Presumably, solar and/or wind. With a Honda just in case?

Tesla's battery probably helps. But then there's the question of how big a Tesla battery and how many square feet of solar cells and how big a windmill.

All of the off-grid solutions I've seen involve significant hammering on the demand side as well as pumping up the supply side.

"30.3 kwh/day average household usage""

That would be extremely expensive--far too expensive to consider for nearly all of us, of course.

"All of the off-grid solutions I've seen involve significant hammering on the demand side as well as pumping up the supply side."

Yes, exactly. No air conditioning, forced air heating or other simple solutions. There'd be clotheslines and unique owner-builds of small utilities all over the place. Chaos!
