Rice, corn, and potatoes.
I have two fine legs, and I'm not ashamed to use them. Usually I use them to walk, for medium distances I bicycle, for the odd long trip (ie. less than once per week) I will break down and use public transit.
While we're at it: my room is lit by two 9 W CF bulbs and I usually limit myself to a single 9 W reading lamp. My usual form of entertainment is the radio and moderately energy efficient laptop computer, not an electricity guzzling television. The house is kept cool by opening or closing the blinds at the right time of day, and through the judicious (ie. infrequent) use of fans, not an electricty guzzling air conditioner. There is still a lot I can do, but it's not a shabby start.
