Frequently Asked Questions

How many alternative fuel and hybrid vehicles are there in the United States?

The U.S. Energy Information Administration (EIA) publishes annual data on the number of alternative-fuel vehicles (AFV) in inventory for four types of vehicle fleets: federal government, state governments, transit agencies, and fuel providers.

EIA publishes data on the supply of AFV and gasoline-electric hybrid and diesel-electric hybrid vehicles from two types of suppliers: original equipment manufacturers and aftermarket vehicle converters.

EIA has estimates and projections for stocks of AFV including electric and hybrid-electric vehicles, in the United States in the Annual Energy Outlook. See tables:

  • Table 40. Light-Duty Vehicle Stock by Technology Type
  • Table 46. Transportation Fleet Car and Truck Stock by Type and Technology
  • Table 50. Freight Transportation Energy Use
