On October 2, 2012, the Environmental and Energy Study Institute (EESI) held a briefing on the growth of plug-in electric vehicles (PEVs) in the United States and on efforts to spur greater transport electrification. The briefing discussed how communities, utilities, private companies, the government and others are leading efforts to put more PEVs on the nation’s roads by capitalizing on new technologies and working to overcome market barriers. The briefing explored ways to foster more rapid PEV adoption across multiple sectors and the different rationales for doing so. Speakers also discussed the various benefits of increased PEV market share; how utilities, communities and other businesses are developing more PEV-friendly areas; and the growing electrification of vehicle fleets.
