Energy is important, but energy independence is a dangerous myth. The U.S. National Petroleum Council recently observed: "There can be no U.S. energy security without global energy security." Oil flows in a world market and events anywhere affect the price of oil everywhere. There is no escaping these oil price shocks. Even if the United States were to substantially reduce its own oil consumption, there would be no immunity from the effects of high world oil prices that would determine domestic energy prices and ripple through the world economy. Geology and politics make the world deeply interdependent and policy should be crafted to promote and secure energy interdependence. Real energy security comes from robust energy systems with diversity and flexibility, not through isolation and energy autarky.
