Green Tip of the Week:  Clean your fridge’s coils
Cleaning the back of your fridge–the coils and electric circuitry–increases energy efficiency.  A refrigerator with dirty coils works harder, and uses 25 percent more energy compared with a fridge with clean coils.   To clean the coils: Disconnect the power; pull the unit away from the wall; remove the grill covering the coils; and use a vacuum cleaner or a bottle brush to clean.
