Quizplus · Accepted Answer

Plug-in hybrid electric vehicles have the potential to significantly reduce both U.S. oil consumption and carbon dioxide emissions. They can run on both electricity from the grid and gasoline, offering the best of both worlds. They can also be charged at home, reducing the need for gasoline and reducing emissions even further. Mass transportation vehicles would also help reduce oil consumption and emissions, but may not be as practical for all individuals and situations. Ultralight vehicles may not provide the necessary safety features and performance capabilities. Fuel cell cars are not yet widely available or practical for most consumers.
