Next, you should continue your energy conservation analysis by examining your home's appliances. They
typically account for about 20% of the home's energy use. The refrigerator, clothes washer, and the
clothes dryer are the major users of this energy. If the appliances are more than 10 years old, you should
plan on replacing them with energy star qualified units.
The refrigerator's energy use can be minimized with routine maintenance. The coil on the unit which is
either mounted on the bottom or the back of the unit should be cleaned at least once per year. This is a
simple matter of removing the dust and dirt with a vacuum cleaner.
You should also test the door gaskets on the refrigerator and freezer. This can be done by placing a
dollar bill in the door opening, closing the door, and trying to pull it out. If the dollar bill comes out
easily, the gaskets should be replaced. It is an easy diy project.
On the clothes washer, you can save energy dollars by lowering the water temperature. It is even better if
you wash your clothes in cold water. With advances in detergents, we can now get our clothes clean without
using hot water and they will even last longer.
The lint trap on the clothes dryer should be cleaned before every load. You should also inspect the vent
for buildup of lent at least once per year. When it is time to replace the unit, you may want to consider
a more efficient heat pump clothes dryer.
