Consider building a solar oven. There used to be some guy who canned tomatoes in his - dr. dougie or some such site. The acidity made homecanning possible.

Solar ovens don't make sense here in Texas. Natural gas is cheap, or depending on your land and contract, maybe free + a check occasionally.

That might be a great idea for some other areas though.

Solar A/C would be great

One thing we do here at the house is cook outside as much as possible during the summer.

Baked bread becomes a fall/winter/spring kind of thing to help warm the house, and summer tends toward homemade tortillas cooked on a comal outside.
