Transportation and Energy: Policy Dilemmas for the Twenty-First Century

Transportation policy is energy policy although the two are developed separately. Twenty seven percent of all energy used in the United States annually is consumed by the transportation sector. The mix of highways vs. rail and private transport vs. mass transit has a direct impact on energy consumption and policy. Transportation is also a major source of air pollution; policies to reduce smog and other pollutants also have an impact on transportation policy and energy policy.
