Transportation Energy Futures Project

The Transportation Energy Futures (TEF) project examines underexplored greenhouse gas-abatement and oil-savings opportunities by consolidating transportation energy knowledge, conducting advanced analysis, and exploring additional opportunities for sound strategic action. Led by NREL, in collaboration with Argonne National Laboratory, the project's primary goal is to provide analysis to accompany the U.S. Department of Energy Office of Energy Efficiency & Renewable Energy's (EERE) long-term transportation energy planning by addressing high-priority questions, and informing domestic decisions about transportation energy strategies, priorities, and investments.

Research and analysis were conducted with an eye toward short-term actions that support long-term energy goals. The project looks beyond technology to examine each key question in the context of the marketplace, consumer behavior, industry capabilities, and infrastructure. More information on the project can be found in the TEF fact sheet, analysis snapshot, annotated overview presentation, and slides-only overview.

Download Tools

In order to complete the TEF project, several tools needed to be developed where existing tools could not be identified to serve the specific purposes.

TEF Data and Sources

As part of the TEF project, the data contained in the reports' tables and figures are available for download into Microsoft Excel via the TEF Data and Sources online data tool. In addition, these tables and figures can be viewed online as Portable Network Graphics (PNG) or in Adobe Reader as PDF documents. Preliminary combined bibliographic information is also available and will be finalized once all reports are released.

The Buildings Industry Transportation Electricity Scenarios (BITES) tool is an interactive framework that lets users explore the energy and carbon implications of altering the current U.S. energy profile. Users can explore a TEF scenario output in BITES using inputs based on study findings, or experiment with different scenario inputs to develop a TEF scenario.


The project is organized in four research areas: light-duty vehicles, non-light-duty vehicles, fuels, and transportation demand. Findings are detailed in a series of nine reports, including:

Light-Duty Vehicles

Non-Light-Duty Vehicles


Transportation Demand

TEF is a collaboration between EERE, the National Renewable Energy Laboratory (NREL), and Argonne National Laboratory (ANL). The project benefited from the input provided by a steering committee that included some of the nation's foremost experts on transportation energy from the Environmental Protection Agency (EPA), the U.S. Department of Transportation (DOT), academic research institutions, and industry associations.
