Maps and Data

The chart illustrates the annual percent change of light-duty vehicles, by fuel type, registered in the United States from 2016 through 2023. Hydrogen fuel cell vehicles (HFCVs) consistently showed the greatest growth in registration counts until 2020. This is largely because initial vehicle registration counts were low. Annual changes are more volatile for vehicle fuel types with small populations, such as hydrogen, compressed natural gas, and propane. From 2016 to 2023, the highest average percentage increases are from electric vehicles with 28.8%, HFCVs with 25.1%, and Plug-in Hybrid Electric Vehicles (PHEVs) with 19.09%. The largest percent decrease is found in compressed natural gas vehicles, averaging -174% because of very limited fueling stations. See relative vehicle population sizes at Light-Duty AFV Registrations, AFV and HEV Model Offerings, by Manufacturer, U.S. Plug-in Electric Vehicle Sales by Model, and the Energy Information Administration's Fleet and Fuel Data.
