Fuel has never been more expensive, the best thing you can do to save money and help the environment is sell one car, or your only car, and use public transportation. It might not always be possible, but if it is you'll be doing yourself and the environment a huge favor. There are roughly two cars on the road for every household in the country.

If every family in the United States gave up one car, it would reduce the amount of carbon dioxide emitted by around 413 billion pounds a year.
