The most efficient laundry dryer is the one you don't use, so opt for line drying whenever possible to save money. When drying laundry in a clothes dryer, make sure you are filling it at least halfway full. If you need to dry only one or two items quickly, try adding a couple completely dry towels to the drum before turning on the cycle. A full—but not overloaded—dryer dries promotes better air circulation, drying clothes faster and leading to lower energy costs. It is important to clean the lint screen and exhaust vent on the dryer regularly to minimize drying time and energy usage.
