Of course, if the rest of the world moves to renewables, which it is, and just the USA remains reliant on oil then that also destroys this benefit. But the USA refusing to help implement renewable energy will definitely slow it down.
It's the only rational argument I can see for this policy. Of course there's the irrational to consider ("real men burn stuff" as Cory Doctorow puts it), and that may be the more important consideration.
