Transportation Energy Use
In U.S.: government subsidies
Although rail & bus transport is twice as energy efficient
for highways & trucking
U.S. autos consume 15% of world oil supply

Transportation Energy Use
U.S. autos consume 15% of world oil supply
The automobiles of the rest of the world consume 7% of world’s oil
Public transportation is more energy efficient
