Source: National Renewable Energy Laboratory 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 other creditable vehicle acquisitions as defined by the program—including medium/heavy-duty (MD/HD) AFVs and LD/MD/HD hybrid electric vehicles (HEVs). The economic downturn of 2008 led to fewer overall vehicle acquisitions, which in turn reduced AFV acquisition requirements. Vehicle purchases rebounded to pre-recession levels, but again dropped during the pandemic.
