Shut the Refrigerator Door, Save 7%

23/08/2013

In most homes, no appliance uses more electricity than the refrigerator, and this simple habit can save you 7% on operating costs. It's a no-brainer.

Don't keep the refrigerator door open any longer than you need to and avoid the cold air from flowing out the door.

The next time you find yourself craving a mid-afternoon snack, make some time to think about what your stomach is asking for before you open the fridge door and stare mindlessly at its contents. The food inside isn't going anywhere and I doubt that anything new will appear in the time it takes you to mentally fix a snack. However, every time you open the refrigerator door, the cold air that keeps your food fresh is running out the door and the warm air from the room is taking its place. This is a problem because now your refrigerator's compressor is going to work hard to drive all that warm air out and bring the temperature back to normal, elevating not only your monthly energy bills, but also your environmental footprint.

According to Home Energy Magazine, door openings account for 7% of your fridge energy use while the Institute of Food and Agricultural Sciences at the University of Florida says that poor open/close habits (like leaving the fridge door open while you soak your bowl of Frosted Mini-Wheats with milk) waste 50 to 120kWh a year. In the long run, 50kWh of energy saved could run your dishwasher 20 times and 100kWh could run your washing machine 50 times, that's almost a free load of laundry every week for an entire year.

So close the fridge door every time you're not directly taking something out of it instead of daydreaming with the door open. Remember, it's not a TV, even if you're into super foods these days, your vegetables are not ready to entertain you with an improvised musical skit.
