Maybe it's been a while since you've shopped for a new refrigerator.
Refrigerators still look pretty much the same from the outside as they
did 10 to 15 years ago. What you can't see, however, is that there
have been some dramatic energy efficiency improvements inside today's
Why should you care how energy-efficient your refrigerator is?
The more energy efficient a refrigerator is, the lower your utility bill will be each month.
New refrigerators are more efficient
ENERGY STAR qualified refrigerator models use at least 20% less energy than required by current federal standards and 40% less energy than the conventional models sold in 2001.
Two price tags
When you are buying a refrigerator, there are really two price tags.
The initial purchase price can be thought of as the down payment.
Sometimes, energy efficient models seem to be more expensive than
less efficient units. Actually, these energy efficient models can be a
better value. Recent design changes include better insulation and
more efficient compressors.
The second price tag is the cost to operate the refrigerator over its lifetime.
You'll be paying the second price tag on your monthly utility bill for about 15
years. Look to the yellow EnergyGuide label to find how much energy the
refrigerator will use annually. Compare the energy use (in kWh) and cost
to operate to other models of similar size and configuration. The more
energy the refrigerator uses, the more it will cost you to operate it.
When you are comparing two models, be sure to compare both first
and second price tags before you buy to figure out the true cost of
buying and operating the refrigerator. You may find that although
one appliance may cost more to purchase, it could end up costing
you less over the lifetime of the unit.
What makes a refrigerator energy efficient?
More efficient compressors and better insulation have greatly improved the
energy performance of new refrigerators. Look for heavy door hinges which
create a good seal for the door; this prevents cold air from escaping.
On models that have the freezer on top, look for an "energy saver" switch.
Switching to "energy saver" mode turns off "anti-sweat" heaters, which can
reduce energy use by 5% to 10%. "Anti-sweat" heaters reduce moisture
between the freezer and fresh food compartments when the weather is
humid, but are not needed most of the year.
Smaller refrigerators use less energy than larger refrigerators -- but it is much
better to run one larger unit than two smaller units.
Look for the ENERGY STAR® label
When you're spending hundreds of dollars on a new appliance, you try
to get the most value for your money. You look for a reliable product
with the features you want and a price you can afford. A great way to
find the right appliance is to look for the ENERGY STAR label.
Appliances with this label have been identified by the U.S. Department of
Energy as being among the most energy efficient products available in their class.
ENERGY STAR-labeled appliances are top performing products that save
you money every day, every month, and for years to come. And, they
help decrease pollution by reducing the demand for electricity.
Models with ENERGY STAR labels will lower the "second price tag" of
on-going energy costs every month for years to come. If an ENERGY
STAR-labeled model costs more than a less efficient model of the same
size, the energy savings will probably pay back the extra cost in only a
