Historical, present, and possible future patterns of energy consumption in the transportation sector are examined for intercity freight and passenger traffic and for urban passenger traffic. The energy-efficiencies among the various transport modes are quite variable. Airplanes are relatively inefficient; cars and trucks are slightly more efficient; and railroads, waterways, pipelines, mass transit, and buses are quite efficient. The energy implications of changes in modal mix for freight and passenger transport are explored using two hypothetical futures.
