1.5 billion dollars to produce 8 million barrels of oil a year. We import 4 billion barrels. To replace one half of that amount would cost us about 375 billion dollars(250 plants x 1.5 billion = 2 billion barrels). Of course that oil then has to be refined.
It seems to me it would be a lot-lot cheaper to open off shore tracts in the U.S. to drilling - oil estimates run at about 60-80 billion barrels. Throw in ANWR and we could replace half our imports for the next 40 years at a fraction of the cost.
We would still need the refineries Clinton closed up even if we opened up drilling in Ca. and Fla.
