For decades, the Department of Energy’s annual Transportation Energy Data Book has tracked trends in U.S. transportation, serving as the definitive guide for industry, policymakers, researchers and consumers. The most recent version is now available online, marking the book’s 40th edition.
Produced and maintained by Oak Ridge National Laboratory in collaboration with DOE’s Vehicle Technologies Office, the widely acknowledged book holds more than 1,000 citations in scholarly reports to date and its impact is felt internationally, too, as automakers use the information to support the engineering of energy-efficient vehicles.
