Finally….low cost of ownership for energy-efficient appliances
It is perhaps not surprising that energy-efficient appliances typically cost more as manufacturers have projected that saving on your long-term energy use is going to more-than-offset any additional amount of money you are going to fork out. From consumers’ viewpoint, it is only prudent to decide on their worthiness based on the cost perspective. The first factor is the selling price of the appliance and the second factor being the operating costs. With this balanced consideration, we would then be able to qualify that if an appliance is really cost effective in the long haul.
Total cost of ownership
When you add the energy-efficient appliance’s selling price to the operating costs, the results will define its true cost, which is also a measurement of its lifecycle cost. “Energy Guide” labels commonly found on electrical appliances such as freezers and refrigerators will give you some indications on how the various manufacturers and models measure up against one another in terms of true costs. The equations below will define further the various cost concepts used in this article.
Selling Price + (Average Lifetime x Estimated Yearly Energy Costs) = Total Lifecycle Costs
Total Lifecycle Cost/Average Lifetime = Yearly Expense on Appliance
“Energy Guide” labels provides the most straightforward means to check and compare operating costs of various models on the market. Federal legislation mandates that all appliances should carry this yellow and black sticker. It tells you the appliance type, maker and model, and projected energy costs per year based on specific utilities rates and usage. Additionally, it shows where that particular appliance stands against the most energy efficient and least efficient models and displays a table listing average costs and different utility rates.
The following is a list of useful features specific to individual appliance types energy efficiency.
- Self-cleaning ovens, with their many insulation layers, are noted for their high energy efficiency.
- Convection ovens are generally quite energy efficient, as heated air is trapped inside, surrounding the food item being cooked. The additional upside here is the even distribution of heat and temperature will ultimately result in food getting cooked faster.
- An oven with a window allows you to check the oven content to prevent overcooking, thus saving energy.
- Wash cycles like “light/china” or “light washed” are energy saving since less water is used over a relatively short time.
- For dry options, select “no-heat” so as not to turn the electric heating elements on, instead the dishes will be left to air-dry.
- Don’t be misguided by Energy Guide ratings when it comes to dishwashers. The rating is decided upon by assuming the dishwasher works through 322 cycles every year, with “normal” on. The frequency you operate your dishwasher, and whether or not it comes pre-installed with additional wash cycle options could result in wild swing in your energy usage.
