Source: National Laboratory of the Rockies' EPAct State and Alternative Fuel Provider Fleet Task

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 (LD) vehicle acquisitions. This chart shows the number of LD AFV acquisitions made by these fleets, as well as medium/heavy-duty (MD/HD) AFV acquisitions. An economic downturn led to fewer overall vehicle acquisitions in 2009, which in turn reduced AFV acquisition requirements. Vehicle purchases rebounded but dropped again in 2020 and remained lower through 2024.
