Washer/Dryer

Applies to Renters  
check Wash full loads - two or three large items, like sheets with a number of small pieces (but don't pack them in) will give you a clean wash without taxing your washer's motor. If you need to wash less than a full load, adjust water lever settings accordingly.
check Sort by color - Use hot water only for whites, hard to clean items and sterilization. About 85% of the energy used by a clothes washer is for heating the water. Use cold water on the rest. Your laundry will be just as clean, fade less and have fewer wrinkles (which might save you some ironing)
check Sort by fabric - separate your laundry into loads of slow and fast drying clothes - Don't add wet items to a load in the dryer that has already been started.
check Don't overdo -An over-used machine uses more energy. Regular clothes need only a 10-15 washing cycle. And over drying will age your clothes and make them stiff, wrinkled and wear out faster. Use the moisture sensor feature on your dryer (if there is one) this way you won't over-dry your clothes.
check Get the lint out - clean the filters on the washer and dryer after every use. Besides making your clothes more attractive, a lint-free machine works more efficiently.
  Check your outside dryer exhaust vent. Make sure it opens and closes freely. If it doesn't close tightly, outside air is getting into your house through the dryer and you will need to replace the exhaust vent.
  Use the sun and a clothesline - Drying your clothes outside will save you 100% of the energy otherwise consumed by your gas or electric dryer.
