Calculate your savings

Go to http://www.bikecommuters.com/gas-saving-calculator/ to see just how much greener your world is when you commute via bike--the green in your wallet, that is.

I get pretty decent gas mileage on my 7-year-old Honda Accord. With gas at $4.04/gallon, and a short trip to work, I save around $175/year by commuting every day via bike (although I do shift to bus when it's incredibly snowy, and that cost isn't included in this).

That doesn't include the savings on the campus parking permit I don't have to buy, the avoided parking tickets during downtown meetings if I drive (I often forget to run back out and plug the meter), and the additional mileage to and from meetings.

Now if I could just kick my latte habit, I'd really be saving some green....
