Former CIA director James Woolsey says America can end its oil addiction (and its reliance on OPEC) by using more electricity, natural gas and biofuels for transportation. "We can move quickly to strike a major blow at oil and OPEC's dominance if we'll adopt a portfolio approach and stop allowing the perfect to be the enemy of the good," he writes. "We can get a long way using existing vehicles, existing technology and affordable natural gas."
