It's not your fault specifically though, it's our fault.
I'm fortunate that I'm in Australia, so my parents now have a hybrid car, a heat pump hot water and solar panels.
I have an EV, electric hot water, solar and home battery but... it was only 2 years ago I was renting, I had no solar panels, gas hot water, petrol car, and no home battery.
I did my best to reduce my electricity usage + paying extra to use the 'green power' option, my car was the smallest/most efficient I could get, I got a motorcycle to reduce the amount of oil use for daily trips to work.
My point of view is that you can only do what is in your capacity to do, and so long as you can say that to yourself you're good, we need more people like you.
