According to scientists, the Earth only has about 120 years' worth of oil left. We need to start looking for other ways to power our vehicles. This book explores four alternatives to gasoline-powered cars--solar-powered, hydrogen-powered, battery-powered, and ethanol-powered cars. Find out their differences, how they are produced, and the challenges involved in converting our planet to alternative fuel sources.
