Electric clothes dryers are a colossal waste of energy. They often draw around 6,000 watts. Six thousand! This is more than a typical heat pump or electric water heater, usually thought of as the hogs of the household. Simply put, you should not use this appliance. Gas dryers are more efficient because they use no electric-resistant heat, but they can still draw around 720 watts. That’s a lot, equivalent to about 60 compact fluorescents (not to mention the energy of the gas). You should plan on getting rid of electric heat dryers and hopefully gas-fired dryers as well if your climate allows.
Solar clothes drying shows this energy source at its finest. It’s a great example of simplicity combined with effectiveness. Hang up something wet in the sun, come back in a few hours, and voilà, it’s dry, clean, and fresh smelling. Like everything, having the proper tools to access this resource goes a very long way in making sure it’s effective and easy to do. Some of this depends on your climate and your own personal habits. We realize some parts of the country have very little sun in the winter, but if you set aside a bit of room, even in a closet or a spare bedroom, clothes hung on racks will dry fairly quickly in a heated house.
