Ever wonder where the biggest chunk of your utility bill comes from? It actually comes from your appliances. Surprisingly, the refrigerator is a huge chunk of utility bills. It's the chief energy guzzling appliance in your home, consuming a whopping 13.7% of house-hold energy, over 1000 Kilowatts of electricity a year, and nearly five times the electricity of a color TV - often nearly as much as a clothes dryer, freezer, and television combined - according to the U.S. Department of Energy. Luckily, newer Energy Star certified models will save you a bundle on utility costs. We often shut off the lights and turn down the heating and air conditioning to save energy, meanwhile, huge amounts of energy are escaping from the refrigerator door as we scour for a midnight snack.
But we are not the only ones to blame, as our out-of-date refrigerators are just as guilty. In fact, according to Energy Star, refrigerators from before 1990 use enough extra energy in a year (over a current Energy Star-rated model) to light a house for four months! Efficiency has been improved with better insulation, more precise temperature and defrost gauges, and more efficient compressors. And improvements have been continuous - models today realize nearly 40% savings in energy use over refrigerators in 2001.
What if you don't want to rush out and buy a new refrigerator? If you just bought a new refrigerator or weren’t planning on buying one anytime soon, I found a few simple steps from reliable sources that can reduce the energy consumption of your existing refrigerator:
• GET RID OF THAT SECOND AND RARELY USED ENERGY HOG LIVING IN THE BASEMENT OR GARAGE!
• Keep your refrigerator at a distance from heat sources such as the oven, dishwasher and direct sunlight so it isn’t working extra harder to maintain a cooling temperature.
• There should be ample space between your refrigerator and the wall or cabinetry behind it so that air can circulate around the condenser coils. And, make sure the coils remain clean so the compressor doesn’t have to work harder.
• Make sure the door seal is tight.
• Try not to keep the door open for extended periods of time.
• Defrost the freezer. Freezer build-up more than ¼ inch can affect the freezer’s efficiency.
• Keep the refrigerator temperature at 37 – 40 degrees Fahrenheit and the freezer at 5 degrees Fahrenheit.
I also found out about an odd suggestion that some of the more daring readers may want to try out. Be sure and let me know how this works. The suggestion is to fill as much empty space in the refrigerator with containers of water. It's supposed to reduce the amount of cold air drop every time the refrigerator is opened. Good luck on that one...
Anyway, where should I get my new refrigerator? Buying an energy efficient refrigerator doesn’t need to be a complicated task. But, given the savings in energy and cost for the modest premium in purchase price, it should be a relative no-brainer. According to Energy Star, the life cycle air pollution reduction of an Energy Star refrigerator is 1,434 lbs of CO2 or equal to .13 cars removed from the road. Annual life cycle cost savings is $72. With this said, buying a refrigerator that can help reduce energy consumption in your home is a good and green choice for your budget and for the environment.
All of the above is magnified when you consider commercial grade appliances and refrigeration units. The statistics on the improvements to those is equally (or exceedingly) staggering. And, don't forget to recycle (or properly displose of) your old refrigerators and appliances. Visit EnergyStar.com to find out where refrigerators can be recycled, or call your local city/county waste management office.

Energy Star Program Working - Let's Keep It Going
The U.S. Environmental Protection Agency (EPA) released a list of U.S. metropolitan areas with the largest number of energy efficient buildings that earned EPA’s Energy Star in 2009. The list is headed by Los Angeles, Washington, D.C., San Francisco, Denver, Chicago, Houston, Lakeland, Dallas-Fort Worth, Atlanta and New York. Energy efficiency saves building owners money and fights climate change.
These cities see the importance of taking action on climate change," said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “Communities from Los Angeles to Louisville are reducing greenhouse gases and cutting energy bills with buildings that have earned EPA's Energy Star."
EPA first issued its ranking of cities with the most Energy Star labeled buildings last year. This year, Los Angeles remains in first place; the District of Columbia picks up second; Denver and Chicago move into the top five; and Lakeland and New York City are new to the top 10.
Continuing the impressive growth of the past several years, in 2009 nearly 3,900 commercial buildings earned the Energy Star, representing annual savings of more than $900 million in utility bills and more than 4.7 million metric tons of carbon dioxide emissions.
Since EPA awarded the first Energy Star to a building in 1999, nearly 9,000 buildings across America have earned the Energy Star as of the end of 2009, representing more than a 40 percent increase over last year’s total. Overall annual utility savings have climbed to nearly $1.6 billion and greenhouse gas emissions equal to the emissions of more than 1 million homes a year have been prevented.
Energy use in commercial buildings accounts for an estimated 17 percent of U.S. greenhouse gas emissions at a cost of over $100 billion per year. EPA awards the Energy Star to commercial buildings that perform in the top 25 percent of buildings nationwide compared to similar buildings. Thirteen types of buildings can earn the Energy Star, including schools, hospitals, office buildings, retail stores and supermarkets.
I've made this comment before, and I'll make it again - the National Green Building Standard Program's Bronze (minimum) level requires that a structure perform 15% more energy efficiently than Energy Star standards. So, with more and more folks building to the National Green Standard, we should see exponential savings in energy usage as we move forward. I would love to see a city like Asheville, one of the Tri-Cities, Boone, Abingdon, or Charlotte on the list as we all continue to push green building ahead. Great progress so far!
