This is a picture of a friend’s Tesla Model S license plate. I too have said goodbye to gas. My Model S now has 7,000 miles on it and I have not bought a gallon of gas for more than six months. Critics say the Tesla still pollutes because most of the electricity used to charge the battery is made with coal or natural gas. That is true today but perhaps not tomorrow. Elon Musk’s vision is to put solar cells on houses and put a Tesla Powerwall in the garage or side of the house. The sun charges the Powerwall. When there is no sun, the Powerwall powers the house. When the car needs a charge, it comes from the Powerwall.
