Electric Vehicles (EVs) reduce or negate gasoline or diesel use in vehicles through integration with the electric grid. Both plug-in hybrid electric vehicles (PHEVs)—which can draw from a battery as well as liquid fuel—and battery electric vehicles (BEVs)—solely powered through electricity—provide the opportunity for power-sharing with the electric grid and can potentially ease the integration of sources of intermittent renewable energy. This is a potentially important technology to help reduce greenhouse gas (GHG) emissions, local air pollution, and vehicular noise.
In this paper, we review studies informing the factors that affect EV adoption. We also review and harmonize studies that develop forecasts of EV adoption over time. We select a set of forecasts that represent low, reference, and high EV adoption and apply them to Hawaii-specific EV and car sales data to provide a preliminary forecast of potential EV adoption in Hawaii.
