We have the technology and ingenuity to reduce the threat of global warming today. Solutions are already available that will stimulate the American economy by creating jobs, saving consumers money, and protecting our national security. By investing in renewable energy and energy efficiency, and increasing the efficiency of the cars we drive, we can take essential steps toward reducing our dependence on oil and other fossil fuels that cause global warming.
Using energy more efficiently and moving to renewable energy (wind, solar, geothermal, and bioenergy) would significantly reduce our emissions of heat-trapping gases. The United States currently produces 70 percent of its electricity from fossil fuels such as coal, natural gas, and oil, but only two percent from renewable sources. Since the burning of fossil fuels releases large amounts of carbon dioxide?the leading cause of global warming?but renewable energy does not, increasing the share of our electricity generated from renewable resources is one of the most effective ways to reduce global warming emissions.
Cars and trucks are another significant source (25 percent) of U.S. carbon dioxide emissions. A serious effort to address global warming must therefore reduce emissions from cars and trucks. Many technologies already exist that can do this, while also creating new jobs in the U.S. automotive sector and other industries throughout the country. In addition, American consumers would save billions of dollars on gasoline, and we would reduce our dependence on foreign oil.
By putting energy efficiency, renewable energy, and vehicle technology solutions in place at the federal level, we can reduce our contribution to global warming while creating a stronger, healthier, and more secure nation.
