·  Change your computer's energy settings - Save 50% in energy costs just by adjusting your computer's power management settings. Look for the power management options in your computer's control panel. From there, select the amount of time your computer should wait before entering the energy savings mode. The shorter the setting the more savings for you and the environment.

·  Replace your car's air filter - A clean air filter can improve gas mileage by as much as 10%, and can save you 28 cents a gallon while reducing the amount of carbon dioxide emissions.

·  Use cold water instead - Doing laundry in hot water costs up to nine times as much per load as washing in cold, while washing in warm costs up to five times as much. Cold water is just fine for cleaning all your clothes, and once again, you will cut down on the quantity of carbon dioxide emissions.

·  Turn down your water heater - The water heater is usually set at 140°. Lower it to 120° and you'll save up to 10% on your electric bill while extending the life of your water heater and pipes by reducing mineral build-up and corrosion.
