Highlights For Edition 36.2

         Thank you for reading the 36th edition of the Transportation Energy Data Book. We hope you find the information you are looking for on transportation and energy. Beginning with this edition, the Data Book will only be posted on-line in both PDF and spreadsheet format on this website. Please utilize the flexibility and convenience of PDF viewing, downloading, and searching. We will continue to update the Data Book as new source data are made available throughout the year, instead of waiting for a once-a-year update. We thank you for your support and flexibility as we make this transition and please do not hesitate to reach out if you have any questions or concerns. I have put together a few highlights of this year's Data Book:

  • Before getting too far into the Transportation Energy Data Book check out Table 1.6 and Figure 1.5 which show some interesting trends on net imports of oil consumed for transportation.
  • Energy use by transportation source can be found in Table 2.3 and broken down by consumption and Btu in Table 2.7 and Table 2.8, respectively. These tables and corresponding Figure 2.6, show how energy is being used across the transportation sector.
  • You do not want to miss Table 2.15 on transportation energy consumption per mile; with our changing transportation environment, these data can inform the energy implications of our behavior and choices.
  • Once you have gotten through the first couple chapters of petroleum consumption and energy use, there is still plenty of information on vehicles (light duty and heavy duty), alternative fuels, fleets, households, non-highway, the economy, and emissions.
  • Note one change in the Data Book in this edition is the conversion factor for converting electricity usage into British thermal units (Btu). For this edition, only end-use energy was counted for electricity, and one kilowatt-hour (kWhr) of electricity is equal to 3,412 Btu. This change affected data in the energy-by-mode series going back to 1970. The rail and pipeline modes were most affected because they use a greater share of electricity than other transportation modes.
  • Check out some highlights of the GREET model (Figure 11.3 and 11.4), and data that helps inform household transportation needs in terms of economics of operating and purchasing vehicles (Table 10.10-10.13), mileage (Figure 8.5 and Table 8.14), and more.


Every figure and table compiled here is thanks to the hard work and diligence of our staff at Oak Ridge National Laboratory, specifically, Stacy Davis, Susan Williams, and Bob Boundy. We hope you enjoy this edition of the Transportation Energy Data Book. If you have any questions or suggestions for future improvements, please let us know.
