I read "no fridge, no heating, no AC" and immediately realized something.
Like, I applaud the dedication, and I hope you find this life fulfilling, but you can't expect _everyone_ to be able to live like that. And not even from a "but some people _neeeed_ sports cars" or other indefensible position, but I mean just from a purely practical position.
You very clearly live in a climate that allows for that. There are _billions_ of people who don't, or won't, shortly, no matter what we do. Heck, you might not live in a climate that will allow for that in the near future.
Again, not to shit on what you're doing, it's honestly interesting and like another commenter said, if you have a blog (maybe solar powered on some upcycled laptop-turned-server?), I'd be interested to read it. But all your choices are personal choices, and they are _really_ low-impact in the grand scheme of things. Even personal swimming pools aren't really moving any appreciable needle, we need broad, sweeping, systemic changes to really make an impact.
Somehow passing regulation to get a large industry to clean up its energy usage or reduce its waste by even 1% is likely going to do more than somehow convincing everyone in the world to give up electric toothbrushes. Please don't feel like I'm telling you to give up on what you're doing! But if you feel like you have any extra energy to try to change public opinion on things, well, I'd prefer if we could get around to the high-impact stuff first, is all.
