65ish, combination of radiant floor heat and a heat pump. We supplement with space heaters when it gets below 18 or so outside.

Besides voting and shopping consciously (and preferably locally), all we can do is be LOUD about the problem. Call your representatives. Vote with your dollars and take to social media loudly to tell companies why you’re not buying what they’re selling if they’re not operating with our collective future in mind. We have to make ourselves somewhat obnoxious if we want to be heard; big companies will ignore you until they can’t ignore you any more.

Also, plant plants. I live on almost an acre that had been cleared a century ago for farm land: now we’re reforesting about half of it with native, non-invasive trees. The rest contains my weird old house, a bunch of perennial flowers, some berry bushes and the biggest vegetable garden I can manage. It’s the best I can do with what I have, and that’s all anyone can really ask.
