Increasing energy costs. There's a reason China pushed heavily into Kazakhstan and Nigeria - they know we've got the Middle East and South America sewn up and they need oil, too. The Hubbert Peak remains controversial and difficult to gauge, but there are reasons to believe the Saudis hit it in 2010.
