Abstract:<br />

This paper del<strong>in</strong>eates the various issues <strong>in</strong>volved <strong>in</strong> develop<strong>in</strong>g reliable estimates <strong>of</strong> the petroleum use<br />

reduction that would result from the widespread <strong>in</strong>troduction <strong>of</strong> plug-<strong>in</strong> hybrid electric vehicles (PHEVs).<br />

<strong>Travel</strong> day data from the 2001 <strong>National</strong> <strong>Household</strong> <strong>Travel</strong> <strong>Survey</strong> (<strong>NHTS</strong>) were analyzed to identify the<br />

share <strong>of</strong> vehicle miles <strong>of</strong> travel (VMT) that could be transferred to grid electricity. Various PHEV chargedeplet<strong>in</strong>g<br />

(CD) ranges were evaluated, and 100% CD mode and potential blended modes were analyzed.<br />

The <strong>NHTS</strong> data were also exam<strong>in</strong>ed to evaluate the potential for PHEV battery charg<strong>in</strong>g multiple times a<br />

day. <strong>Data</strong> from the 2005 American Hous<strong>in</strong>g <strong>Survey</strong> (AHS) were analyzed to evaluate the availability <strong>of</strong><br />

garages and carports for at-home charg<strong>in</strong>g <strong>of</strong> the PHEV battery. The AHS data were also reviewed by<br />

census region and household location with<strong>in</strong> or outside metropolitan statistical areas. To illustrate the lag<br />

times <strong>in</strong>volved, the historical new vehicle market share <strong>in</strong>creases for the diesel power tra<strong>in</strong> <strong>in</strong> France (a<br />

highly successful case) and the emerg<strong>in</strong>g hybrid electric vehicles <strong>in</strong> the United States were exam<strong>in</strong>ed. A<br />

new vehicle technology substitution model is applied to illustrate a historically plausible successful new<br />

PHEV market share expansion. The trends <strong>in</strong> U.S. light-duty vehicle sales and light-duty vehicle stock<br />

were evaluated to estimate the time required for hypothetical successful new PHEVs to achieve the<br />

ultimately atta<strong>in</strong>able share <strong>of</strong> the exist<strong>in</strong>g vehicle stock. Only when such steps have been accomplished<br />

will the full oil sav<strong>in</strong>gs potential for the nation be achieved.<br />
