This graph shows the energy consumption (in gasoline gallon equivalents [GGEs]) of the U.S. transportation sector by mode and fuel type for the year 2019. For the most part, each transportation mode is dominated by a different fuel type. Light-duty vehicles use the most GGEs of fuel per year, followed by medium/heavy trucks and buses. Water transportation relies mainly on residual fuel oil. Pipeline is the only mode of transportation that uses predominately non-petroleum fuels.
