Umm, ANWR will not be able to supply the US with the same amount of oil that we get from Saudi Arabia. How much oil is in ANWR you ask? According to a
report from the ANWR website, there is anywhere between "600 million barrels at the low end to 9.2 billion barrels at the high end." If measures passed this year and the US were to go ahead with drilling there, all of the reports I have seen have estimated that the earliest real oil production would not start until, again at the earliest, 2010-2012. Drilling in ANWR would also affect more than 1% of the land there, according to their website, it would affect at least 8% of the land in the reserve.
How much oil does Saudi Arabia have? According to a
report from the Saudis, they have about 1.2 trillion barrels left in their reserves. That is one heck of a difference.
An interesting factoid from a
US Navy website is "boosting the fuel efficiency of cars in the United States by a mere 1.5 miles-per-gallon would save more oil than is estimated to lie under the Arctic National Wildlife Refuge."
