This article describes sources of energy efficient appliances and energy efficiency ratings for appliances.

We explain where to find the energy efficiency ratings for a home appliance like an air conditioner, water heater or refrigerator, and we explain how to interpret what the efficiency rating means.

We include a Directory of Appliance Energy Efficiency Rating Programs and Labeling Regulations from Around the World.

Where to Find Appliance Energy Efficiency Ratings

One third of its condenser coil cooling ability was blocked.The current energy efficiency ratings of building appliances are available from a variety of sources listed here, including energy efficiency of air conditioners, clothes dryers, clothes washers, fans, refrigerators, stoves, water heaters, well pumps, etc. Our page top photo shows an A.O.

Question: Finding Energy Efficient Appliances

I'm frequently asked about the energy efficiencies of appliances by those for whom I'm building a house. Usually I suggest that they check Consumer Reports, or the label of the product. This is pretty poor help.

I have just been asked about energy efficiencies again, this time for domestic water heaters. Can you give me a list of names (without favoritism) of the most energy-efficient electric water heaters?

Answer:

Checking the U.S. Department of Energy's Energy Guide on each appliance is one way to find the most efficient one, but it can be time consuming.

"The Most Energy Efficient Appliances" is a document published by the American Council for Energy-Efficient Economy. Top-rated water heaters (and the most efficient water heaters - the only kind listed there) include many models from Mor-Flo, Therma-Star Products, E-Tech, Ruud, and Rheem. [DJF note: Be sure you are comparing "apples to apples" when comparing appliances by noting the water heater energy source (electric, LP gas, natural gas, home heating oil, solar, etc.), the water heater size, its recovery rate, and other performance measures, not just the annual energy or fuel use.]

Other sources of energy efficiency directories include

The US DOE document linked-to above points out that in a typical U.S. home, appliances and home electronics are responsible for about 20% of your energy bills. These appliances and electronics include the following:

Note that this list excludes heating and central air conditioning equipment - major energy consumers in most homes.

Many countries and governments in addition to the U.S. provide some excellent energy rating guides that can benefit consumers anywhere, as many appliances are sold worldwide:
