"It is now possible to build cars that are powered by a combination of electricity and alcohol-based fuels, with petroleum as only one element among many. My administration is going to put in place a series of policies that will ensure that in four years, the average new American car will get 300 miles per gallon of petroleum. And I fully expect in this period to see cars in the United States that get 500 miles per gallon. This revolution in energy use will reduce dramatically our dependence on foreign oil and achieve pathbreaking reductions in carbon-dioxide emissions, far below the targets mentioned in the Kyoto accords.
