With EVs, you may not even need any hydrocarbon for cooking and heating. I've seen some existing ICE van conversions that run induction cooking purely off of solar and about $1k of lithium batteries in warmer climates. Some also have fancy floor heating that run off of auxiliary batteries, so it should be a piece of cake for EVs. With proper insulation, I imaging you can go pretty far on solar alone between plugging-ins. Just gotta reserve enough for the trips to town.
