Smart Investing in Energy-Saving Appliances

When replacing older appliances, consider new, energy-efficient models. They often cost little or no more than energy guzzlers and will produce significant savings on your energy bill. In some cases, the energy, cost and environmental savings of a new model are sufficient reason to replace an older appliance that still works well.

Refrigerators - New, energy-efficient refrigerators use as little as 400 kilowatt hours of electricity per year, half the energy use of standard fridges from the early 90s and one quarter of those from the early 1980s. At current electricity rates of 6 cents per kilowatt hour, that ancient fridge can cost more than $100 a year to run, compared to about $25 for an energy-efficient model. If the freezer in the new fridge (top-mounted freezers are the most energy efficient) is large enough, you can perhaps unplug your chest or upright freezer and save another 500 kilowatt hours per year.

Front-loading washing machines - More properly known as horizontal-access machines, these washers use about half the water, electricity and detergent of a top-loading washer, plus cut dryer costs because their high-speed spin cycle wrings more water from clothes. For a family of four, the extra $200 or $300 on the purchase price will pay for itself in energy savings in a couple of years.

Dishwashers - Shop for dishwashers with built-in heat boosters, which raise their hot water heat to at least 60 degrees Celsius (140 degrees Fahrenheit), This allows the temperature on your hot water tank to be set at an energy-efficient 50 degrees C. (120 degrees F.)

Toilets - A conventional toilet uses 15 litres or more of water per flush. Newer, low-flow toilets (costing between $150 and $300) use between three and six litres. The City of Calgary is offering a $50 rebate to eligible city residents who buy a new, water-efficient toilet.

Furnaces - A high-efficiency furnace (generally more than 90 per cent efficient) saves gas and electricity (the furnace fan is the second-highest user of electricity in most homes). It can reduce fuel costs by up to 30 per cent over a conventional furnace, which for many families could mean $500 less in annual heating costs.

Hot Water Tanks - Upgrading to a higher-efficiency model could save you more than $90 in water heating costs per year.

Windows - Leaky, inefficient windows can allow one-quarter of your house's heat to escape. Double-glazed, low-emissivity windows are expensive but can cut home heating costs considerably and provide more comfortable indoor temperatures in winter and summer.
