Projected decline in U.S. transportation sector fuel use, 2010–2050

http://www.rmi.org/RFGraph-Projected_decline_in_US_transportation_sector_fuel_use
America's vast transportation system can continue growing and improving all without oil. In 2050 we’d rely on superefficient, lightweight vehicles and planes to move ourselves and our goods. For the remaining 3.1 Mbbl/d of liquid fuel demand not supplied by electric propulsion systems, 2nd and 3rd generation biofuels (or, in trucks, natural gas if desired) could be substituted for oil.

Value of U.S. transportation sector savings, 2010–2050

http://www.rmi.org/RFGraph-Value_of_US_transportation_sector_savings
Transitioning to a more efficient transportation system by 2050 will cost, all told, $2 trillion in 2010 present value, but will save $5.8 trillion. This includes the cost of building the distribution infrastructure needed to support a fleet of autos running on a mix of electricity and hydrogen, less avoided investments in domestic oil supply.

For autos in particular, the savings from investing in Revolutionary+ vehicles can be clearly observed between 2027 and 2050.
