Earthships!
"Earthship" homes in northern New Mexico are beyond cool. Made partly of trash (old bottles, cans, tires, etc.), these homes don't need heating or cooling--in the cold/hot desert! They can maintain 70F all year round (or a bit cooler, if you like). Earth-sheltering and great insulation are the keys. On a more-local level, governments should insist on a basement or daylight basement in every home! Even above grade on a flat lot, a daylight basement home is practicable. And saves hugely on energy costs. The design can be traditional (as our winery/farmhouse was--it was European traditional but earth-sheltered in back and on the sides, and solar-powered), or as wacky as you can imagine. https://www.wbur.org/hereandnow/2024/06/24/earthships-sustainable-housing?utm_source=npr_newsletter&utm_medium=email&utm_content=20240626&utm_term=9551098&utm_campaign=news&utm_id=54187699&orgid=135&utm_att1=
