Best Habit: Turn off your screen savers and set your computers to sleep or standby mode after 30 minutes. A desktop screen saver can use 68 watts of electricity, while a sleeping computer can use just three.
Favorite Product: Energy Star-qualified decorative lights. If every set sold in the United States met that criterion, we'd prevent a billion pounds of greenhouse gas emissions and save $80 million on electricity in one year.
