UNCERTAIN TRANSPORTATION ENERGY FUTURES--U.S. COMPARED WITH OTHER REGIONS OF THE WORLD, 1970-2000

TL;DRAbstract

The U.S. uses more transportation energy in total and per capita than any other region of the world. Over two-thirds of this energy is used to move passengers whereas most other regions use only about a fourth of their transportation energy to transport people. The U.S. is comparatively energy efficient in regard to movement of freight and this relative efficiency is expected to improve by the year 2000. Transportation has had greater importance in the overall energy picture than might be assumed on the basis of its share of total energy use. As will be seen, transportation appears to offer significant opportunities for increased efficiency of energy use.
