Table 2.5
Domestic Consumption of Transportation Energy by Mode
and Fuel Type, 1998
Most of the source data were given in gallons. Fuel use was converted to Btu using the conversion factors
in Appendix B.
Highway
Automobiles
Motorcycles
Buses
Total gallons of fuel taken from DOT, FHWA, Highway Statistics 1998, Table VM-1. These
were distributed as follows: 97.% gasoline, 1 .O% gasohol, and 1.3% diesel.
Percentages were derived from the DOE, EIA, Office of Markets and End Use, Energy
End Use Division, Household Vehicles Energy Consumption 1994, August 1997, p. 46.
Natural gas data are from the DOE, EIA Natural Gas Annual 1998, Table 1; transit bus
natural gas was subtracted from the total and the remainder was assumed to be light
vehicle use. Automobiles were assumed to use 25% of light vehicle natural gas use.
Methanol use was estimated using data from DOE, EIA, Alternatives to Traditional
Transportation Fuels 1998, Washington, DC, 1999, Table 12.
DOT, FHWA, Highway Statistics 1998, Table VM-1. For conversion purposes, fuel for all
motorcycles was assumed to be gasoline.
Transit:
APTA, 2000 Transit Fact Book, 2000, Washington, DC.
Non-diesel fossil fuel consumption was assumed to be used by motor buses,
In twcity:
Eno Transportation Foundation, Transportation in America 1999, Seventeenth Edition,
2000, Lansdowne, VA, p. 56. For conversion purposes, fuel for all intercity buses
was assumed to be diesel fuel.
School:
Gasoline andDiesel - Eno Transportation Foundation, Transportation in America 1999,
Seventeenth Edition, 2000, Lansdowne, VA, p. 56. For conversion purposes, fuel
for school buses was assumed to be 90% diesel fuel and 10% gasoline based on
