These guys pooh poohing ANWR's reserves will be singing a different tune when their tank runs dry someday and it costs $350 to fill it up.
It's doubtful that the US can ever become 100% self-sufficient, but it's inarguable that we can produce at least another 3-4 MMbbl/day...assuming only that we're ALLOWED to do so by the Marxists masquerading as ''environmentalists''.
And that figure, btw, doesn't include the 1-2 MMbbls/day that will become available from the Athabaskan project in 8-10-12 years, nor the potential off the Western coast of S. America.
Point is that, for at least 30 years (minimum) we can distinctly lower the cost of the marginal barrel of crude to levels that will remain compatible with a growing economy -- if we get our thumbs out.
And, if we should somehow become sensible about undertaking a doubling or trebling of nuclear generation capacity, and (as long as I'm fantasising here) find an improved method of coal liquification and/or gasification, we could very easily (albeit not cheaply, in terms of absolute dollar cost) be sitting pretty for a century or so.
