Benefits of PHEVs
1. Greenhouse gas emissions
28% of GHG emissions from transportation (EPA)
2. Air pollution
22,000-52,000 deaths per year from air pollution (JAMA)
3. Oil dependency
Cost U.S. economy ~$0.5 trillion in 2008 (Greene)
5CMU EPP Advisory Board Meeting | 3-14-2011 Jeremy J. Michalek
How much can xEVs help?
xEVs offset gasoline use
Reduces oil dependency
xEVs change emissions profile
Fewer emissions associated with gasoline production and combustion
More emissions associated with battery and electricity production
xEVs change location of emissions
Location doesn’t matter for GHGs, but…
Damage done by air pollution highly depends on where it is released (population density, etc.)
6CMU EPP Advisory Board Meeting | 3-14-2011 Jeremy J. Michalek
Location drives air pollution damage

Net life cycle costsOptimistic: Plug-in vehicles slightly less expensive over the life. Costs drive comparison, not damages
Pessimistic: Plug-in vehicles could cost much more while causing more damage

Oil dependency
Oil Supply Disruption
Externalities estimated at $0.11/gal (Brown and Huntington)
Not enough to change trends
Market Power
US Monopsony effect:$0.22/gal (Leiby)
Military spending:
$75-$90 billion in 2009 (RAND) : $0.24-$0.28/gal
But…
Spending is nonlinear: Marginal reductions may have near-zero effect on military spending
Less than half of each bbl oil produced is used to make gasoline – large reductions require coordination

Other externalities
Rebound effect
Lower operating costs may encourage more driving
Higher congestion costs
Higher accident rates
These externalities have higher associated costs than emissions (Delucchi)
Will range issues combat rebound effect?
14CMU EPP Advisory Board Meeting | 3-14-2011 Jeremy J. Michalek
Take awayEmissions damage reduction potential of plug-in vehicles
Upper bound: Hydro electricity
BEV reduces damages $1000 over HEV
Lower bound: Coal electricity
BEV increases damages $6000 over HEV
Worth the cost?
Damage reductions are small compared to ownership costs
Across most scenarios, electrification is better only when it saves consumers money
If it’s cheaper, market will drive adoption
If it’s not, emissions benefits don’t justify the extra cost
Oil dependency
Externalities, monopsonyeffect, and marginal security spending not enough to tip the balance
Small is Beautiful
More batteries more green
Large packs are underutilized
Extra emissions from production, weight
HEVs and PHEVs with small battery packs are most efficient and robust
Offer a good solution across a wide range of scenarios
Reduce more GHGs per dollar spent
