The Transportation Energy Data Book is going ECO-FRIENDLY!
Beginning this year, the Data Book will not be printed in hardcopy format, but
will be posted on-line in both PDF and spreadsheet format on this website. One advantage to this is that updates to the report
can be made throughout the year when new source material becomes
available, instead of waiting for a once-a-year update. Feel free to print the full
PDF document if you continue to prefer a hardcopy.
