i have been doing alot of research into this subject,
What is the cost per mile for 'fuel'?
as the price of gas goes ever higher.
(i've been told by summer we will be paying $4.00 for a gallon of gas) 
Good old supply and demand. There is a huge demand for gas, so they've got us. It is a real shame.....
As far as electric vehicles go - if and when we all have to use them, then the demand will be for electricity. If the vehicles are rechargable, then the price of electricity will sky rocket even worse that it is now.
i have been looking into all of this, not just the price of gas, but my boyfriend wants to build an ev, it would be similiar to the tesla, but for a single person, like something you can use to get back and forth to work and run some errands.
he has already built one (using regular car batteries) but with the lithium ion batteries that the tesla is using, the range would be far supioror.
the only thing is the cost of the lithium battery itself.
the next few paragraphs i got from another post at an ev site.
it mentions how in the long run, even using coal power plants for the electricity. it would still be more effient.
it starts off mentioning the tesla, which sells for $100,000
Ok guys there is one reason and ONE reason only that the tesla costs so much money. The answer is a number (no its not 42)
6,831
Know what that is? Thats the result of Chevron buying and sitting on the patent for the only currently tried and true VIABLE battery tech for EV's
Thats how many CONSUMER lithium battery cells Tesla had to use to make there car work. Nearly 7 thousand freaking batteries!!!
Do the math. Imagine the consquences and you will QUICKLY see why this car costs that much money.
GM had a battery that could take a car over 100 miles for $4500
THERE cost to build this car ? $80,000 BEFORE you say thats a lot consider it was a bleeding edge hand made prototype of which LESS than 1,000 were made
If you ramped up production of an $80,000 prototype to millions of cars it would cost less than $10k to make them......
want 200 miles? easy toss in TWO $4500 battery packs. I have seen people spend more than 9k on leads for HALF that range. 10+ years later (today) it would cost a lot less than $4500
Sadly this patent does not expire till 2015 so until someone invents something NEW (and the only ones with the REAL money to do the R&D needed also have the MOST to lose by doing so...)
Result - We get screwed. GM sold controlling stock in ovonics (battery tech) to Texaco. Chevron bought Texaco.
Chevron has controlling share in ECD Cobasys and has VETO rights on ANY usage of the battery technology. IE NO EV's allowed.
EV's at minimum 6 times more efficient than Gas cars so EVEN IF you transfer the pollution to a COAL plant (recharging the car) your producing 1/6th the pollution.
To top that off Nano Solar just shipped there first solar panels for 90cents a watt IF they can get them to US consumers at or near that price then consider this.
$1600 for the grid tie in and $500 for the solar panel and driving your car would not become FREE and 100% pollution free. That $500 panel would produce MORE E each month than you would use charging your car. You see that E to the utility so its makes power for you from morning to night and you get the credit on your E Bill. that credit will be larger than your deficit to charge the car. 100% free to Drive 100% pollution free. Its a win win.
I want an EV so badly I am dieing for one. I would save over $3 grand a year in gasoline!!
