The U.S. Energy Information Administration (EIA) publishes historical annual data for 2002 through 2017 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. The data include supply of AFV, gasoline-electric hybrid vehicles, and diesel-electric hybrid vehicles from two types of suppliers: original equipment manufacturers and aftermarket vehicle converters. No newer data are available because EIA has discontinued the Annual Survey of Alternative Fueled Vehicles, Form EIA-886.
More recent data on AFV are published in Oak Ridge National Laboratory’s Transportation Energy Data Book; see Chapter 6: Alternative Fuel and Advanced Technology Vehicles and Characteristics.
EIA publishes model-based estimates and projections based on various assumptions for stocks of AFV including electric and hybrid-electric vehicles in the United States in the Annual Energy Outlook. See the Reference case tables:
