The Plan, published in 2008, is his second on energy independence and oil addiction. Dismissing energy independence as a distant goal, The Plan confronts the looming crisis of a sudden oil interruption. The U.S. consumes about 20 million barrels of oil per day, some 70 percent imported, and if only 2 million were interrupted for a protracted period of a month or more, the nation would be thrown into economic chaos. The Plan explains that severe weather such as hurricanes and pinprick terrorism at pipelines could not cause such a disruption, but that a blockade of the Strait of Hormuz could. The book then outlines the step-by-step day-by-day rationing, vehicle retrofitting and fuel switching needed to survive such disruption, based on the policies and precedents of International Energy Agency and our own history of emergency response. While some 28 other oil consuming nations have adopted emergency measures, American policymakers have not even discussed a contingency plan.
