New refrigerators can save on energy costs

August 07, 2008

I have a 15-year-old refrigerator and think that it’s probably about time to replace it. What should I look for when shopping for a new fridge?

Buying a new refrigerator is a big deal, because in the typical home the refrigerator is the third largest energy user. So it makes sense to look not only at the many features that are available, but also take a look at the energy use of each model you’re considering.

After you’ve found the basic features you’re looking for, a very easy place to start is by looking for models with the Energy Star symbol. Energy Star refrigerators are at least 15 percent more efficient than the minimum federal efficiency standards. That’s because they use improved, high efficiency compressors. The new models also have more insulation and more precise temperature and defrosting controls, saving even more energy.

And if a refrigerator is more than 15 years old like yours, you’ll find that a new Energy Star qualified model will only require about half as much electricity as the old one.

As you compare the different models, you’ll also want to take a look at the yellow Energy Guide label on each model. That will allow you to compare the estimated cost to operate the various models. And while Energy Star models typically cost a bit more, the money you save on your electric bill typically more than makes up for any difference.

Rebates available

Clark Public Utilities is offering $25 back on the purchase of qualifying Energy Star refrigerators from a participating Clark County retailer. To receive the rebate you also must agree to recycle your old refrigerator, which the utility will do for free.

Why? Simply put, old refrigerators and freezers from the 1960s, 1970s and 1980s are big energy wasters. Buying old appliances at garage sales or passing them on to relatives just compounds energy inefficiency.

In addition to inefficient energy use, the refrigerant used in old refrigerators and freezers is classified as a greenhouse gas and should be kept out of the environment. Without proper decommissioning, the refrigerant gas in these old units often escapes into the environment, creating problems with the earth’s atmosphere.

While there’s no rebate on Energy Star models, if you’re in the market for a freezer, be sure to look for the Energy Star label.

Energy Star qualified freezer models use at least 10 percent less energy than required by current federal standards. You’ll find qualified upright freezers with automatic or manual defrost and chest freezers with manual defrost only.
