TG,

Thanks for the quick figures. I try to make sure things are as apples to apples when talking to others.

I have a friend with a Tesla. He also did a home solar install. His numbers look good, but gets kinda butt hurt when you ask him about how long it will take him to pay back the subsidies he got to install it. When he parks at home and charges off his solar/battery array, or goes to work which gives him a 'free' charging station his personal point in time costs look very good. But he never is willing to figure in the costs outside of his direct miles driven energy costs.

Last spring he traded his minivan off on a second Tesla. He then went on to say that driving both Teslas on a family camping trip (because he couldn't fit everything in one) was still more efficient than taking the minivan.

And this guy is smart. Computer science guy, always good with money. Bought and flipped a house by 22, had his second house paid off by 27. But he is so hung up on solar, wind, and EV as the only way forward.
