I'm sorry you feel so powerless about these things. I hope you find a way to take control in ways that matter to you.

Personally, I've largely replaced my car usage with walking and biking, installed insulation in uninsulated parts of my home, got more comfortable with less heating/cooling (sweaters and fans), and am planning to upgrade to a heat pump when the time comes.

It's good to live your values without falling into scrupulosity, both for yourself and others.
