Thanks! Good stuff.
There is no "miracle oil field" that will fix everything for the U.S., not ANWR, not Bakken, not the Gulf. But when you start adding up all the resources currently "off-limits" (mostly for environmental reasons), it does start to look fairly significant.
I don't think it's realistic in the near term to achieve independence from all imports. We're talking all electric vehicles and nuclear power for that.
I do think we have a fairly good chance at much better independence from the Middle East, particularly in light of new finds in Brazil. We already get most of our imports from Canada and Mexico, and I think "hemispheric independence" is a reachable goal.
