The numbers will dramatically increase as our population grows from 32 million today to 38 million in the next 15 years. Vehicles emit the vast majority of the harmful pollutants that cause the smog that affects the health of all of us. All of the easy and cheap solutions to clean up our air quality problems have been employed, especially from stationary source emissions. Most of California's factories, businesses and power plants have the best available control technology for pollution. Cleaning up vehicle emissions is both fair and necessary as the transportation sector is called upon to reduce pollution.
Electric vehicles are only part of the overall strategy to clean up mobile source emissions.
This much cleaner form of gasoline goes on sale next year. We expect that gasoline will remain the dominant transportation fuel for many years. But California needs to reduce its dependence on one fuel source to make it less vulnerable to supply disruptions. We have done that in our electricity production. Twenty years ago about two-thirds of all California's electricity came from burning oil.
