Perhaps the next most important appliance in your kitchen—after your cooker—is your refrigerator and/or freezer. They are almost always on. Here are some tips to save on energy:
- If your refrigerator is more than 15 years old, it might be time for a replacement. Look for an Energy-Star model, which will use anywhere between 15 and 40 per cent less energy than older models.
- To save energy, you should make sure your refrigerator and freezer are set to an ideal temperature. Recommended temperatures for refrigerators are between 2-4 degrees Celcius, and for freezers, the ideal temperature is -18 degrees Celcius, according to the FDA.
- Let your leftovers cool before storing them in the fridge. Hot food will raise the temperature in the fridge, making it work extra hard to maintain its cool temperature.
- Your freezer will work more efficiently when it’s full. The frozen items bunched together make it easier for your freezer to maintain its icy temperature efficiently.
- Ensure your kitchen refrigerator and freezer doors are airtight. There is a plastic liner in the doors that keeps the cold air inside and the warmer air out.
- Due to normal wear and tear, replace the liner (also known as the gasket) every couple of years. Don’t forget to check it every now and then.
