Transportation accounts for about 28 percent of U.S. energy consumption.
Petroleum accounts for nearly all (about 97 percent) of the transportation sector's
energy use. Petroleum is a major component of transportation costs, and its usage affects
the environment. Because more than half of the U.S. petroleum supply is imported,
there are also national security concerns for assuring petroleum supplies.
