Energy, no matter how its created, ain't free even solar isn't free

Thats correct MrB.
Even this Tesla owner said that he will never break even given the cost of the car - however he does start saving the second he drives the car.

Much like Solar the investment is all up front - however and like the car the more you use it the faster it pays it self off. So if you are able to max out your solar and combine that with a all electric car, the break even point will come much much sooner.
