Keep Like Items Together
Different types of clothes require different lengths of time in the dryer to become completely dry.  Your sturdy blue jeans, for example, will take much longer to dry than your regular cotton t-shirt.  It makes sense therefore to wash and dry like items together.  This saves you from running your dryer much longer than is necessary.

Use Energy Saver Settings
There are energy saver setting on almost all new large appliances, including dishwashers, refrigerators, washers, and dryers.  You can save as much as $400 every year just by using these settings.

Watch Out for Energy Eating Setting
Many dishwashers come with the handy setting labeled “rinse and hold”.  Many people use this cycle between wash cycles of the dishwasher when it is not yet full.  The problem with this cycle is that is uses up to eight gallons of water, and your dishes still need to be washed.  If you use “rinse and hold” just once a week you will use as much as 1600 gallons of water each and every month.
