Clothes dryers account for up to 20 percent of all energy use in the United States. So if you want to save energy at home and reduce your carbon footprint, one of the easiest switches you can make is to using a clothesline instead of a dryer. There’s just no comparison between the net-zero draw a passive solar clothesline has and the energy used by dryers—even the new, “energy-efficient” models.
But there’s also no comparison between clotheslines and dryers when it comes to speed, wrinkle and lint removal, and the potential for laundry mildew when it’s humid or raining out. So in the instances when you are set on using a dryer, here’s how to be as energy-efficient as possible.
Situate your dryer on an outside wall.
The less distance your dryer’s exhaust has to travel, the more energy you’ll save. You want as few elbow bends and feet of dryer piping as humanly possible for maximum efficiency.
