Older appliances — even those made in the 1990s and early 2000s — can use significantly more energy than today’s ENERGY STAR® models. When it’s time to purchase a new appliance, look for the ENERGY STAR label and use their most efficient settings. Also, be sure to keep them well maintained.
Hot water heating accounts for about 90% of your washer’s energy use, so wash laundry in cold water whenever possible. Wash full loads or, if you must wash a partial load, adjust the water level. Clean your dryer’s lint trap before every load, and avoid over-drying clothes. Better yet, line-dry your laundry.
Depending on local water quality, many homeowners can effectively wash all their clothes in cold water. Fabrics generally last longer if dried on a clothesline or rack, too.
Avoid common energy wasters when it comes to dishwashing. Rather than pre-rinsing dishes, which can use up to 20 gallons of water alone, simply scrape food off dishes and into your garbage disposal. Run only when full, avoid water-heating boost when possible, and choose the no-heat drying option.
Start by unplugging that older extra refrigerator in the garage or basement. Older-model refrigerators cost you an average of $150 per year to run. Make sure your kitchen refrigerator is in a cool place, away from direct sunlight and heat-generating appliances that can make it work harder. Keep it no colder than about 35 to 38°F, with plenty of air circulation behind it. Don’t stand with the door open; grab what you need quickly and shut the door. Make sure the door seals fit tightly against the doorframe.
While a microwave uses less energy than a range or oven, balance its use with other small appliances, like slow cookers and toaster ovens. When using your oven, preheat only when required, make sure seals are tight, and don’t open the door while cooking.
Just by using the right size pot on a burner, you can save about $36 a year if you have an electric range. And using a microwave to cook small portions can reduce the energy you use for cooking by as much as 75%!
