The gasoline and diesel fuel used in highway modes accounts for the majority of transportation energy use (81.5%). Air is the largest non-highway mode, using jet fuel for nearly all of its energy use.
Domestic Consumption of Transportation Energy Use by Mode and Fuel Type, 2013
Note: Civilian consumption only. Totals may not include all possible uses of fuels for transportation (e.g., snowmobiles). Residual fuel oil is heavier oil which can be used in vessel bunkering.
