13 13 Oil Consumption (US) US 2030 oil production = 2.72 B bbl/yr (14.3 Quads); US 2006 non- transportation consumption = 2.25 B bbl/year (6.16 M bbl/day) [Ref: AEO 2008]

14 14 Urban Air Pollution Costs Source: Argonne National Laboratory GREET 1.8a

15 15 Monetized Externalities Societal Costs Calculated for: –Urban air pollution (average of six sources for costs)* –Greenhouse Gas emissions ($25/tonne to $50/tonne) –Oil/Balance of Trade/Military protection costs ($60/bbl) * VOC = $6.59/kg; CO = $1.28/kg; NOx = $13.84/kg; SOx = $29.74/kg; PM-10 = $53.74/kg; PM 2.5 = $134/kg.

16 16 Societal Cost Reduction Factors* *Reduction Factor defined as societal cost of gasoline ICEV/cost of alternative vehicle; Near-term = now to 2020; Mid-term = 2021 to 2050; Far-Term = 2051 to 2100

17 17 Key Assumptions Assume success for all options Assume stringent climate change constraints

18 18 Assume Success! Fuel Cell Vehicles: –FCVs are durable & cost competitive –Hydrogen infrastructure & cost are competitive & available –Hydrogen sources become green over time

19 19 Assume success! Plug-in Hybrids: –Deep discharge batteries allow up to 52 miles all electric range & 65% grid energy –75% of all vehicles have access to night- time charging outlets –The electric grid becomes green over time

20 20 Assume success! Ethanol Plug-in Hybrids: –Same as for gasoline PHEVs, plus –Ethanol is made from cellulose –Ethanol production capacity grows from 7 billion gallons per year from corn to 120 billion gallons per year from cellulose
