Sorry for taking some time to respond to some of the messages back, kinda miss this thread and have been away from the from the forum for a little.
What happens if you use the free energy from the solar panels on your house? That seems to me to be more efficient than oil-powered cars and certainly cheaper (assuming you don't but a ridiculously expensive electric car that will take you a lifetime to recoup the costs of).
I mean, solar panels aren't free and shouldn't be thought of as producing 'free energy' the energy is only free once your investment (which is rather large to get these installed) is paid off. Until that is done, you should do some calculations to see how much you invested to put those up, maintain, etc.
But I do see your point, though people fall into this trap of thinking that energy is free if it's solar -- while it's not. You without a doubt reduce costs after them being paid back after 30 yrs (depending on financial situation, of course) but there's no such thing as instant free / free lunch.
