Highlights

Edition 36 of the Transportation Energy Data Book Released
The Transportation Energy Data Book (TEDB) is a compendium of data on transportation with an emphasis on energy. Designed for use as a desktop reference, the TEDB was first published in 1976 and has continued to Edition 35. The TEDB is produced by Oak Ridge National Laboratory for the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy.

2016 Vehicle Technologies Market Report
The 2016 Vehicle Technologies Market Report was released May 25, 2017 via the web. The report details the major trends in U.S. light-duty vehicle and medium/heavy truck markets. This report is produced by Oak Ridge National Laboratory for the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy.
