Analysis of the penetration of plug-in electric vehicles (PEVs) per capita reveals that, to the surprise of no one, California is far ahead of the rest of the United States. Based on data from Navigant Research’s recently published Electric Vehicle Geographic Forecasts report, 7 of the 20 areas with the most PEVs on the road in 2015 are in the state.
As show in the below table, California’s seven metropolitan statistical areas are near the top of the list for PEVs sold per 100,000 residents. California’s route to success has included substantial investments in PEVs and EV charging infrastructure through incentives, project grants from the California Energy Commission and other state institutions, and by providing PEV access to HOV lanes. However, the coveted HOV stickers are nearly gone, so it would not be surprising if PEV sales in the Golden State slow unless new stickers are made available.
PEVs on the Road per 100,000 Residents
The regions on this list have many things in common that make owning a PEV favorable, including demographics like age and higher average incomes that lean toward PEV ownership. All of the states wherein these regions lie have some form of incentive for buying or driving an EV or for purchasing a charging station, often in the form of tax credits or the ability to drive in HOV lanes. Also, nearly all of the areas on the list were recipients of charging infrastructure funded by the Department of Energy’s EV Project and ChargePoint America projects, which deployed thousands of Level 1-2 and direct current (DC) fast charging stations between 2010 and 2013. The exceptions that were able to also create demand in PEVs are Honolulu, Denver, and Miami, although each area has received some federal funding for EV programs.
Investments in public EV charging infrastructure by federal or state agencies (or increasingly utilities) have resulted in greater PEV awareness by the general public, as well as increased PEV sales as potential buyers feel greater confidence knowing that they can charge at familiar spots around town. Conversely, states without investments in EV charging infrastructure have seen much less PEV penetration.
