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.
Our electric vs. internal combustion engine chart shows the overwhelming advantages of electric .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.
