Transportation accounts for 71% of total U.S. petroleum consumption and 33% of total greenhouse gas emissions.

The U.S. Department of Energy has designed the Transportation Energy Futures (TEF) project to examine underexplored oil-savings and greenhouse gas–reduction opportunities by aggregating transportation energy knowledge and estimating opportunities.

The project addresses high-priority questions to inform transportation energy strategies, priorities and investments. Research and analysis identifies near-term actions that support long-term energy goals. 

It looks beyond technology to examine the marketplace, consumer behavior, industry capabilities and infrastructure.

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.
