APPLIANCES

The only way to ensure that you are purchasing an energy efficient appliance is to look for the Energy Star label. The average new 2011 refrigerator used less electricity than a comparable model did in 1972 yet cost much less, despite more and better features.
To find Energy Star products click here and consider following these additional tips on appliances:

Dishwashers
-Older dishwashers require a water supply of at least 130F. Newer dishwashers have a small water heater to boost water temperature to about 140F in order to save standby losses of the water heater.

Clothes Washers
-Horizontal-axis machines save 50-75% of both energy and water compared to most vertical-axis models.
-ENERGY STAR qualification requires 1.42 MEF since in 2004. (MEF is the Modified Energy Factor, compared to EF)

Clothes Dryers
-Cleaning the dryer lint filter after each cycle minimizes drying time
-Dryer and vent should be thoroughly cleaned every few years.
-The vent should be a smooth metal pipe, sealed at joints with silicon caulking. (The picture here is an example of incorrect venting as seen in many households.)

Refrigerators and Freezers
Refrigerators account for 9% to 15% of a household's total energy consumption, running day and night 365 days a year. According to ENERGY STAR, the most efficient standard refrigerators use less than 500 kW-hours of electricity per year.
-Keep freezers as full as possible.
-Defrost the freezer when 1/4 inch of frost has accumulated.
-Minimize refrigerator or freezer door openings.
-Clean the coils on refrigerators and freezers with a soft brush once a year.
-Keep the vent clear of dust.

When selecting a new refrigerator, consider the following:
-Automatic defrost models waste energy. Choose a manual defrost model.
-Side-by-side refrigerator/freezers use more energy than units that have the freezer compartment on the top or bottom.
-Upright freezers use more energy than chest freezers.
-Operating two refrigerators uses far more energy than one larger model.

Stoves
Something new is appearing on the horizon: A Croatian-Swiss inventor Dusko Maravic has invented a new kind of pot whose bottom, rather than warping when heated, stays perfectly flat and in full contact with a computer-controlled resistance-heated ceramic element. The result: better, faster cooking and large electricity savings. Further big savings are available from smarter controls and from several innovations in pots and their lids.
