Energy Efficiency Tips
for Appliances

GENERAL TIPS FOR APPLIANCES

  • An energy efficient appliance may cost more to purchase, but can save you money and energy over its lifetime.
  • Remember: appliances have two price tags -- the purchase price and the operating price. The less energy efficient an appliance is, the higher its operating price will be.
  • The EnerGuide label shows how much energy an appliance consumes in a year of normal service, so you can compare the energy efficiency of each model.
  • For major appliances, an indicator arrow on the left side of the EnerGuide Label's bar scale means lower operating costs and long-term savings.
  • On appliances, the EnerGuide label shows the energy consumption in kilowatt-hours (kWhs) per year. The lower the number, the more energy-efficient the appliance.
  • On major appliances, you may see the yellow and black U.S. EnergyGuide label alongside the black and white Canadian EnerGuide label. The Canadian and U.S. governments are working toward harmonizing these labels to make it easier for manufacturers.
  • Unplug electronic devices and re-chargers when not in use and save an extra 2 per cent in energy costs.  All electronics with a digital clock, including microwaves, continue to use electricity even when switched "off."  Use a power bar to ensure "off" is really "off."  Phantom load accounts for about 10 per cent of all electricity used in Canadian homes.

Oven

  • Microwaves use approximately 50 per cent less energy than conventional ovens; they are a very efficient appliance for defrosting and cooking small meals.
  • Thaw frozen foods before cooking; they will require less cooking time and less energy.
  • Check the reflectors under your stovetop burners. The cleaner they are, the better they will reflect the heat.
  • Once water reaches the boiling point, it doesn't get any hotter. You can turn down the burner and still maintain a boil.
  • Use the right size pots and pans and element size for the job. The pots and pans should have clean flat bottoms, straight sides, and tight fitting lids. Cook with the lid on.
  • Unless you're baking, preheating the oven isn't necessary especially for roasts or casseroles. When appropriate, use the broiler. It saves energy and requires no pre-heating.
  • When baking in glass or ceramic utensils, lower the heat by 14°C (25°F) because they transfer heat better than some metals.
  • Cooking just a small quantity? Consider using a microwave, toaster oven or slow cooker. They are much more efficient.
  • Self-cleaning ovens generally have upgraded insulation. This is convenient and also more energy efficient for regular cooking.
  • A clean oven is more efficient and accurate.
  • Use the timer on your stove so your oven will turn off immediately at the end of the cooking time you have selected.

Fridge / Freezer

  • Never place your fridge beside your oven, dishwasher or other heat sources. It will have to work harder to stay cool.
  • Place your freezer in a cool, dark spot to boost its energy efficiency.
  • Set the temperature of your fridge at about 3° C (37° F), your freezer at -18° C (0° F). Colder temperatures are unnecessary and just waste energy. Place a quality thermometer inside and adjust the dial accordingly.
  • If your refrigerator has an energy saver switch, adjust it to provide maximum energy savings without causing condensation on the outside of the unit.
  • Every few months, vacuum your refrigerator's condenser coils as dust and dirt can impede its performance.
  • Check to make sure your fridge and freezer doors are properly sealed. Close the door on a piece of paper and then try to remove the paper. If it slides out or moves easily, adjust the door or replace the seal.
  • Many people have kept old fridges running either in the basement, a storage room, or at the cottage. Unplug a second fridge when you don't need to use it and you could really save over $150 per year on your electricity bill.
  • The temperature for a freezer should be about -18°C (0°F). 
  • An uncrowded fridge works more efficiently than a crowded one. However, freezers work best when they are two thirds full.
  • Don't open the refrigerator door more often than necessary. The cool air escapes quickly.
  • Freezers should be located in a dry, heated, insulated area that maintains a steady temperature. Avoid porches or garages. Variable outside temperatures may cause compressor damage.
  • Spread packages out for freezing and then pack them closely together. Only freeze the amount of fresh food a freezer can handle. About 5 kg per 100 litres of freezer space (3 lbs. per cu. ft.) in a 24-hour period is right.

Dishwasher

  • Always use the energy saver option on your dishwasher.
  • Avoid running small loads in your dishwasher.
  • If your dishwasher has the option, choose air drying rather than heat drying. If not, stop the machine before the drying cycle starts and open the door to let dishes air dry.
  • Simply scrape your dishes before loading them into your dishwasher instead of using hot water to rinse them.
  • Keep the filter at the bottom of your dishwasher clean to keep your machine running efficiently.
  • Many new dishwashers have internal booster heaters that allow you to turn down the temperature on your hot water heater to 47° C (115° F).

Washer / Dryer

  • Wash laundry in cold water whenever possible.
  • Always select your washing machine's cold water rinse --rinsing in hot or warm water won't make your laundry any cleaner.
  • Wait until you have a full load before doing laundry.
  • Although they are more expensive, front-loading washing machines use one-half to one-third less energy than traditional models because they use less water.
  • Remove and clean the washer's agitator once a month. Clean the filters of both water hose inlets on the back of the machine once a year.
  • Be friendly to the environment. Look for phosphate-free laundry soap.
  • Try using an outdoor clothesline to dry your laundry -- clothes will last longer and smell great!
  • Drying two or more loads in a row makes the most of the heat already generated by your dryer.
  • Use the sensor cycles instead of timed dry and save energy while extending the life of your clothes. This will help you avoid over-drying. If you have manual timing controls experiment until you've determined how long it takes to do a typical load.
  • Avoid partial loads. On the other hand, don't overload. Try to organize your washing and drying so you are doing full loads.
  • Never vent your dryer indoors. It can be very dangerous due to moisture, fibres, and chemicals in the dryer exhaust.
  • Clean the filter every time between loads. A clogged filter can damage your dryer, lower its efficiency, and become a fire hazard.
