Energy Efficiencies of the Transport Systems 730066
Would a marked curtailment in allowable petroleum use seriously slow down present growth rates for transport activity? This paper explores a doubling of transport output in 25 years while holding oil consumption under the present 90 billion gal per year. By shifting some intercity and urban traffic to modified systems with better energy efficiency, higher traffic volumes can still be moved. Surprisingly, if the right choices are made, personal vehicle ownership and auto travel could continue to increase, as could air travel; and actual door-to-door travel convenience could be maintained or improved.
