Fleet Performance Data

Fleet performance data collected through the Federal Automotive Statistical Tool (FAST) website reveals trends in Federal agencies' alternative fuel vehicle (AFV) acquisitions, petroleum reduction efforts, and alternative fuel use. These data can help agencies analyze their fleets' performance in meeting Federal mandates.

The Federal Energy Management Program (FEMP) posts Federal fleet performance data sets in various formats, including charts and maps, data sets, and annual reports that can be downloaded, saved, and manipulated for individual research. Data sets are organized into the following topics:

The methodologies section explains which agencies, vehicles, and fuels are covered and tracked through FAST. For more information about the data, analyses, and trends presented, please contact Margo Melendez at the National Renewable Energy Laboratory (NREL).

 

EPAct 1992 Alternative Fuel Vehicle Acquisition Requirements

A series of charts compares Energy Policy Act of 1992 (EPAct 1992) AFV acquisition requirements with total AFV acquisitions and additional AFV credits for covered Federal agencies.

EPAct 2005 Waivered Alternative Fuel Vehicles

An interactive map displays the E85 AFVs waived from meeting Energy Policy Act of 2005 (EPAct 2005) alternative fuel use requirements. Data is based on waiver approvals for FY 2015 (submitted in FY 2014), which were primarily granted to AFVs housed more than 5 miles or a 15-minute drive from an E85 refueling station.

Federal Fleet Vehicle Inventories

The following fleet vehicle inventories are organized by fuel type, vehicle type, agency, and year. Total vehicle counts are for domestically based vehicles and include law enforcement and emergency vehicles.

Federal Fleet Fuel Consumption Data

Fleet fuel consumption is measured in gasoline gallon equivalents (GGE). One GGE contains the same amount of energy as a gallon of gasoline regardless of the actual volume (or density) of fuel.

Methodologies

NREL's analysis of Federal fleet performance uses data derived from FAST. Certain covered Federal departments and agencies are required to report annually on the number of alternative fuel vehicles in their fleets as well as the total number of all vehicles, whether light-, medium-, or heavy-duty. They are also required to specify and quantify the type of fuel used. Total vehicle counts and alternative and petroleum fuel consumption amounts are for domestically based vehicles, including law enforcement and emergency vehicles.

  • Army Corps of Engineers
  • Court Services and Offender Supervision Agency
  • Department of Agriculture
  • Department of Commerce
  • Department of Defense (including Army, Air Force, Navy, U.S. Marine Corps, and Defense Agencies)
