Under the Energy Policy Act of 1992 (EPAct) and subsequent regulations, certain vehicle fleets operated by state agencies or alternative fuel providers are required to acquire alternative fuel vehicles (AFVs) as a fraction of their light-duty vehicle fleet. This chart shows the number of AFV acquisitions these fleets made from 1992 through 2022. Flexible fuel vehicles that operate on high-level blends of ethanol continue to be the most frequently acquired vehicle. This is likely because they can conveniently be refueled on gasoline when ethanol is not available and because vehicle manufacturers offer the flex fuel option on the models most frequently acquired by fleets. Furthermore, the marginal cost increase of acquiring a flex fuel vehicle over a conventional gasoline vehicle is minimal or nonexistent. Continuing the trend from recent years, fleets are also acquiring electric vehicles, which now make up the second most acquired AFV type.
