Estimated Consumption of Alternative and Replacement Fuels for Highway Vehicles

KEY:  N = data do not exist.

^a EIA's data collection does not produce enough survey coverage for local and municipal governments, private fleets, and household vehicles, EIA only publishes the fuel use and the number of vehicles for four fleets; federal government, state governments, transit agencies, and fuel providers. The total fuel used by these four types of fleets do not represent the U.S. total for AFV inventory and fuel use. These values should not be aggregated.

^b A high-level ethanol blend containing 51%-83% ethanol...

Motor Vehicle Fuel Consumption and Travel

Certificated Air Carrier Fuel Consumption and Travel

KEY:  R = revised; U = data are not available.

^a  Aircraft are aircraft carrying passengers or cargo for hire under 14 CFR 121 (large aircraft-more than 30 seats) and 14 CFR 135 (small aircraft-30 seats or less). This definition is more encompassing than that in the Federal Aviation Administration (FAA) Aviation Forecast- jet aircraft, 60 seats or more carrying passengers or cargo for hire. Beginning in 1990, the number of aircraft is the monthly average reported in use for the last three months of the year. Prior to 1990, it was the number of...

Energy Consumption by Mode of Transportation

KEY: Btu = British thermal unit; N = data do not exist; R = revised; U = data are not available.

^a Domestic operations only.

^b Includes fuel used in air taxi operations, but not commuter operations. Data for 1996 are estimated using new information on no respondents and are therefore not comparable to earlier years. See the accuracy statement in the appendix for more detailed information. 

^c Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories...

Fuel Consumption by Mode of Transportation in Physical Units

KEY: kWh = kilowatt-hour; N = data do not exist; R = revised; U = data are not available.

^a Domestic operations only.

^b Includes fuel used in air taxi operations, but not commuter operations. Data for 1996 are estimated using new information on no respondents and are therefore not comparable to earlier years. See the accuracy statement in the appendix for more detailed information. 

^c Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories and...

U.S. Energy Consumption by the Transportation Sector

KEY:  Btu = British thermal unit; R = revised; Z = a value of zero, or value too small to report.

^a Sum of primary consumption, electricity, and electrical system energy losses categories.

^b Sum of biomass, natural gas, and petroleum categories.

^c Beginning from 1980, small amounts of coal consumed for transportation are included in industrial sector consumption.

^d Consumed in the operation of pipelines, primarily in compressors, and small amounts consumed as vehicle fuel.

^e...

Domestic Demand for Refined Petroleum Products by Sector

KEY:  Btu = British thermal unit; R = revised.

Production, Production Shares, and Production-Weighted Fuel Economies of New Domestic and Imported Automobiles

KEY:  mpg = miles per gallon;  P = preliminary; R = revised; SUV = sport utility vehicle; U = data are not available.

U.S. Oil and Gas Pipeline Mileage

KEY: N = data do not exist; R = revised.

^a Excludes service pipeline. Data are not adjusted to common diameter equivalent. Mileage as of the end of each year.

^b Before 1985, data include field line mileage.

^c The jump in 2022 data is due to the newly defined Type C regulated gas gathering lines, as defined by PHMSA here: https://www.phmsa.dot.gov/technical-resources/pipeline/gas-gathering/...

Natural Gas Pipeline Profile

KEY: N = data do not exist; R = revised; U = data are not available.

^a Total does not sum from components due to the omission of a line from source table for depreciation and other noncash expenses. 

^b Figures obtained by addition / subtraction and may not appear directly in data source.

^c Industry total includes integrated and combination company totals in addition to distribution and transmission company totals.

^d Excludes service pipeline. Data are not adjusted to common diameter equivalent. Mileage as of...
