I disagree with what he says about co2 and the old “you have to make electricity with something” argument. It wasn’t until I bought a Tesla and did the math myself that I realized how inefficient gas cars are compared to an electricity generating power plant. My equivalent mpg with my electricity rate is something on the order of 150-180 mpg. For trips where we can charge at home (most of our miles) it is a 1/3 of the cost of our Prius to drive.
