The next big technology change in cars is electric vehicles, which studies have shown are less polluting than all-gasoline engines, particularly if cars are charged at night. In the next two years, a number of cars will be coming out from the big incumbents to start-ups that will offer a big leap in efficiency. Depending on your driving habits, you may never need to go to gas stations.
Of course, the best way to green your ride is to leave your car at home and use an alternate mode of transportation, such as biking or mass transit.
