Replacing old appliances really can save energy – and money. How much money? These calculations, based on Energy Star labeling, help you find out.

Over the past decade, many Americans have seen the need to reduce their energy consumption. Some people have chosen to pursue this lifestyle change in order to live green and save the planet. In many cases, though, this reduction in energy consumption is driven by the savings that can be achieved by decreasing energy costs. Opportunities to deliver these energy savings occur throughout a home: replacing old appliances with new ones can create a significant return on investment (ROI).

The U.S. Department of Housing and Urban Development's (HUD) 2009 American Housing Survey (AHS) determined that 66% of U.S. households have a dishwasher. It's not really any surprise that two-thirds of our homes have a dishwasher when you consider that today's Energy Star dishwashers will save you time, water, and utility costs. Depending on how often you use your dishwasher, you can expect an average life expectancy of nine years, according to the Study of Life Expectancy of Home Components, prepared in 2007 by the National Association of Home Builders (NAHB). Performing simple maintenance tasks will help your dishwasher last longer than expected and will also reduce the likelihood that your dishwasher will cause water damage to your home.

According to the Study of Life Expectancy of Home Components, which was prepared in 2007 by the National Association of Home Builders (NAHB), the average life expectancy of a washing machine is 10 years. While washing machines are not made to last forever, performing simple maintenance will help to ensure they last as long or longer than expected, and will actually reduce the likelihood that your washing machine will be the cause of significant water damage to your home.

Dryers remove moisture by blowing hot air over wet, tumbling clothes. The hot, moisture-laden air is exhausted outside the home through a dryer vent duct. According to the Study of Life Expectancy of Home Components, which was prepared in 2007 by the National Association of Home Builders (NAHB), the average life expectancy of a clothes dryer (gas or electric) is 13 years. Dryers are a fairly simple appliance with a long life expectancy as compared to other appliances, but present both personal and property hazards. Timely dryer maintenance will reduce potential problems and ensure it is functioning as excepted.
