Modern societies rely upon prodigious amounts of oil for transport activity. The impacts over the near term of increasing oil scarcity and higher prices on transport will be among the major challenges facing humanity and will require a revolution in thinking about how we move people and goods. Transport Revolutions analyzes five prior episodes of rapid and radical change in the way people and goods travel. It examines the worldwide state of transport today, especially its energy use and impacts, positive and negative. The authors then show how ample movement of people and freight could be sustained beyond 2025 with much-reduced dependence on oil, focusing on the United States and China.
