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, gasoline-electric hybrid vehicles, 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:
