1. Build a clothesline
Next to your refrigerator, your dryer is likely the biggest energy-guzzling appliance in your house. And while we wouldn’t ask you to store your food in a vintage icebox, an old-fashioned clothesline is actually a pretty good idea. (If that sounds too retro, think of it as a “solar dryer” instead.)
You can buy a pulley kit like the one pictured here at the hardware store. Or you can order the components online. But it’s easy to make a traditional clothesline yourself, using 4×4 or 6×6 pressure-treated posts for the uprights and 2x8s for the cross arms (which don’t need to be pressure-treated). Simply notch the posts to receive the cross arms, set them in concrete, and run the lines on eye hooks between them. A 4- or 5-foot cross arm should give you enough room for five lengths of line, nicely spaced.
