Increasing transportation efficiency is the best place to start efforts to reduce emissions of carbon dioxide (CO2), which is a primary culprit in global warming. Of all CO2 emissions in the United States, about 33 percent comes from transportation.
Our electric vs. internal combustion engine chart shows the overwhelming advantages of electric cars — plug-in hybrid vehicles and all-electric vehicles (EVs) — over gasoline vehicles. With gasoline-electric hybrid power and all-electric power, we can achieve significant cost and environmental savings. By adding more batteries and recharging capability to gasoline-electric hybrid vehicles, we can have plug-in hybrids that offer the range of hybrids (500 miles or more), plus the benefit of all-electric power for short trips, which dramatically reduces the amount of gasoline used. EVs require no gasoline whatsoever and, when recharged from renewable energy sources, produce zero total emissions.
