America's vast transportation system can continue growing and improving—with 90% more driving, 118% more trucking, and 56% more flying in 2050 than in 2010—even as it phases out oil.
In 2050 we’d rely on superefficient, lightweight vehicles and planes to move ourselves and our goods. Autos would run on electricity or hydrogen, trucks and planes on 3.1 Mbbl/d of 2nd and 3rd generation biofuels (or, in trucks, natural gas if desired). The expanded mobility and delivery services provided would cost $3.8 trillion less than business-as-usual in 2010 net present value.
