also, the U.S. consumes ~18 MBbls/day of oil...the latest estimate of U.S. 'Proven Oil Reserves' is 35 BBbls of oil...(per
the "EIA")
18 MBbls x 365 = 6.6 BBbls/yr...
35 BBbls/6.6 BBbls = 5.3 years of U.S. oil remaining (more from "Unproven Reservers")
How much oil, and for how long, should the U.S. provide to the EU?...Note: our gas reserves are higher...we have ~10.6 yrs of Proven Reserves at current consumption levels...per EIA data.
btw, our recent surge to "Energy Independence" has been made possible by improved "Fracking" technology, which, btw, uses a LOT of 'Fresh Water'...like ~140 Billion gallons each year (enough to serve two cities the size of Chicago)...and a lot of it is being used in the increasingly arid Western States...just saying.
Note: the 'ANWR' Project is assumed to have 4.3 - 11.8 BBbls of oil...or, optimistically, 1.8 additional years of reserves at current consumption levels.
