The demand for transportation fuels in California is increasing at a rapid rate. It is projected to grow by almost 35 percent over the next 20 years. Unless we change our habits, petroleum will be the primary source of California's transportation fuels for the foreseeable future, and as demand continues to rise and in-state and Alaskan petroleum supplies diminish, California will rely more and more on foreign imports of crude oil.

Nearly 100 percent of the state's transportation system is fueled currently by fossil fuels. Moving toward a more diversified range of fuels and supporting the advancement of higher efficiency vehicles is one of the goals of the state's programs.
