Wash clothes in cold water and air or line dry them. Use rechargeable batteries. Recycle. Compost. Take mass transit. Ride your bike. Carpool. Drive 55. Walk to the store. Set your fridge to 37°. Set your freezer to 5° and keep it full (use containers filled with water). Turn off the dry cycle on your dishwasher. If it's yellow, let it mellow. Unplug "energy vampires" like TVs, DVD players, and iPod chargers when not in use.
