Palin got her “degree” in energy as Gov. of Alaska. The real world really is the best place to learn - and she beat the best.
The energy policies that Palin implemented as Guv were all undone.
The Palin pipeline(AGIA) was dead before she left office and was the primary reason she left.
Palin's oil tax increase(ACES) was undone by Parnell and Sullivan which was subsequently upheld by Alaska voters.
Palin's attempt to force the Exxon consortium to develop Pt Thompson was undone by the courts.
This doesn't mean she can't serve as energy secretary. Historically, that is a political appointment. Obama was the first and only to hire technical people for the job.
