Refrigeration is responsible for 6% of your home’s energy use. Being a single appliance responsible for all this energy use, the fridge is an ideal place for some Energy Saving Ideas.
Much like Lighting, Refrigerators and Freezers produce heat, which works against you when you try to cool your home. Once again you get double savings for reducing your refrigerator’s energy consumption.
Here’s how to save energy on refrigeration and reduce electric bill:
Make sure your refrigerator is set to the correct temperature. 45÷F (7÷C) are enough for the fridge, while 0÷F (-18÷C) are sufficient for the freezer.
A damaged seal lets the cool air out, making your refrigerator work harder to keep itself cool.
When your refrigerator works harder it uses more electricity. It also produces more heat, meaning that you need more A/C, and the compressor’s life is shortened.
Have a look at the sealing gasket. If it is worn, torn or doesn’t look flush – replace it. Even small gaps can affect performance dramatically.
Check the air passages, vents and coils for dust which clogs them, and vacuum if necessary.
Clean vents will make your refrigerator and freezer use less electricity, and will also make them last longer.
Do this once, preferably twice a year.
so that the hot air it generates can circulate well.
A well circulated refrigerator will consume less energy.
Let it cool down to room temperature on the counter top instead prior to putting it in the refrigerator/freezer (unless the recipe tells you to do it).
instead of defrosting them in the microwave on under running water. When defrosting food in the refrigerator you get to save electricity.
First, you save by avoiding the microwave use. Second, the frozen food helps to cool the refrigerator as it thaws, lowering its electricity demand.
A side benefit is slow defrost, which is better for the food.
Make sure your refrigerator and freezer are not standing under direct sunlight.
Put them in a cold spot, as far as possible from any heat source such as radiators, ovens or any other heat producing device.
If you can manage to put them against an outside wall – even better. Outside walls are cooler then inner walls, and the heat generated by the refrigerator or freezer can escape outside more easily.
Don’t just stand in front of the refrigerator or freezer, staring at it while trying to make up your mind.
Every time your refrigerator or freezer doors are open, you loose a lot of energy.
Try to decide what you want before opening the doors.
One of my favorite energy saving ideas:
Develop a habit of labeling clearly the items in your freezer, so that you can retrieve the food you are looking for quickly as possible, loosing less energy.
Unless you have a no frost refrigerator or freezer, you need to defrost it on a regular basis, or when it gets too much iced up (more than 1/4″ or 6 mm thick).
An Iced up freezer makes the cooling unit work harder and use more electricity, wasting more energy than needed.
Keep your freezer full. An empty freezer will loose a lot of cold air every time you open it, and new hot and moist air will replace it, resulting in more ice buildup and more energy lose.
And here is the most original of all the energy saving ideas I’ve come across: If you don’t have enough food to fill the freezer, put empty container boxes inside to do the job.
If your fridge is from the 70s, replacing it with an ENERGY STAR qualified model can save you over $200 each year on your utility bills.
Replacing a fridge from the 80s will save you more than $100 each year! Use the ENERGY STAR Savings Calculator to find out exactly how much money you can save by replacing your existing refrigerator.
