It wouldn't be that simple.
The way to get off mideast oil is to drill our own, we have enough to last over 200 years if we would just harvest it.
That isn't going to happen as long as democrats are in, I think the Saudis own them, lock stock and barrel. (no pun)
We probably have more in the Rockies alone than all Saudi reserves, unfortunately it happens to be on federally owned land.
Yesterday the Obama administration announced a delaying tactic which will put off the possibility of new offshore oil drilling on the Atlantic coast for at least five years: The announcement by the Interior Department sets into motion what will be at least a five year environmental survey to determine whether and where oil production might occur.
We might make progress toward using nat gas in automobiles and it sure as heck would make a lot more sense than the volt but then it couldn't be used in diesel engines and that's what moves the freight via trucks, locomotives pulling trains and towboats pushing barges.
Then there is another thing, petroleum is a huge portion of our economy other than just gasoline.
For instance, a partial list of products made from Petroleum (144 of 6000 items):
One 42-gallon barrel of oil creates 19.4 gallons of gasoline.
The rest (over half) is used to make things like: Solvents, Diesel fuel, Motor Oil, Bearing Grease, Ink, Floor Wax, Ballpoint Pens, Football Cleats, Upholstery, Sweaters, Boats, Insecticides, Bicycle Tires, Sports Car Bodies, Nail Polish, Fishing lures, Dresses, Tires, Golf Bags, Perfumes, Cassettes, Dishwasher parts, Tool Boxes, Shoe Polish, Motorcycle Helmets, Caulking, Petroleum Jelly, Transparent Tape, CD Players, Faucet Washers, Antiseptics, Clothesline, Curtains, Food Preservatives, Basketballs, Soap, Vitamin Capsules, Antihistamines... etc, etc etc.
BTW, Obama's (evidently permanent) ban on drilling in the gulf (while 23 other nations do), has had, at the very least, ten times the negative effect on our economy as the oil spill he used for an excuse for such an inane policy.
