I put solar panels on my roof a few years ago. Not a complete solution but I do believe it makes a difference. Also slowly moving to all electric appliances. I now have an induction range instead of gas. And all energy star appliances.
I hope my next vehicle will be an EV. When my gas mower dies I'll buy electric.
I am starting the ball rolling on better insulating my 1950s house.
All incremental improvements, nothing too radical.
