Welcome
to this 26th edition of the Transportation Energy Data
Book. Over half of these editions have been produced by
Stacy Davis. DOE is grateful for her dedication and
the skill she has brought to this effort.
I would like to bring to your attention some of the data
that is new or of particular interest: |
| 1. |
The U.S. share of world oil consumption
reached its lowest value in 2006. The U.S. share of 24.2%
is much lower than the share in 1970 of 31.4%. (Table 1.4) |
| 2. |
The
transportation share of U.S. energy use reached 28.4% in
2006 which is the highest share recorded since 1970. (Table
2.1) |
| 3. |
New data on the fuel use of lawn and garden equipment
are presented in Table 2.10; these data are from EPA’s
NONROAD2005 model. |
| 4. |
The Energy Information Administration has not published
new data on alternative fuels and alternative fuel vehicles
in the last two years. (Tables 2.3, 6.1, and 6.2) |
| 5. |
Due to more stringent data restrictions imposed by R.L.
Polk, the latest number of vehicles by age that we are
allowed to publish is 2001. (Tables 3.5 & 3.6) |
| 6. |
The American Metals Market discontinued the survey which
collected information on the average materials in a domestic
car; therefore, the 2003 data are the latest available.
(Table 4.14) |
| 7. |
New data on the travel of heavy trucks less than two years
old is presented in Figure 5.1. |
| 8. |
The Census Bureau has discontinued the Vehicle Inventory
and Use Survey; the 2002 data are therefore the latest
data available. (Tables 5.4–5.9) |
| 9. |
New
data are presented on the additional driving cycles which
will be used by the Environmental Protection Agency
(EPA) beginning with model year 2008 to determine the fuel
economy ratings for new vehicles. (Table 4.25 & Figures
4.5–4.7) |
| 10. |
New
data on daily travel of household vehicles are presented
in Tables 8.11-8.13 and Figures 8.3–8.5. |
| 11. |
The
Department of Transportation has discontinued the National
Household Travel Survey; therefore, the 2001 data are the
latest data available. (Tables 8.5–8.13 & 8.17) |
| 12. |
The
EPA has not published new data from the National Emissions
Inventory since the 2002 data; thus, Tables 12.1–12.11
remain unchanged. |
| 13. |
The
amount of data on hydrogen and hydrogen vehicles has been
reduced in this edition of the book; we would like readers
to use the newly available Hydrogen Data Book (hydrogen.pnl.gov/cocoon/morf/hydrogen/article/103)
for up-to-date data and information in this area. |
| I
hope you find value in this data book. We welcome suggestions
on how to improve it. |
