I dont want to talk for all traidsmen but I thought it was hilarious when I was told how energy is made on demand. If you drive to the chicago plant you will see lines of trucks filled with gas to burn to make electricity bc we use so much. Do want to add this is bc of businesses who use a lot more then your house. But I would say the most waisted energy is on homes. As business want to same as much money and use 3 4 plus phase electricity. But homeowners leave lights on use powerfull equipment that should be 3phase but it's not and other waist we dont need light lighting our lawns and holidays. But in terms of cars the most environmentally friendly thing to do is advocate for used cars and better reliability. I work on my own car and these chains have only rose the price on repair as people dont know how to do it themselves
