There are getting to be more and more choices when it comes to purchasing a green vehicle. The EPA has a great Green Vehicle Guide. This guide allows you to look up a specific vehicle to learn more about its air pollution, fuel economy and greenhouse gas scores. You can also search for the greenest vehicles so you have good information when you go out to the car lots.
The US Department of Energy has some great information on hybrids, gas mileage and the most efficient vehicles available. You can even look up the lowest gas prices in the area or plan your next trip to be the most fuel efficient possible.
