The key is to handle each item as little as possible. You can do that by hanging clothes on plastic hangers once, while they are wet. Once the clothes are dry, you just grab the batch and move it to a closet, without any of the folding, hanging or sorting that takes time when you take stuff out of a dryer. A drying rack can make socks and underwear even easier to dry.
People talk about about recovering the lost art of line-drying clothes the way our grandparents did it. But after experiencing modern convenience, it's hard to go back. My goal is to make line drying almost as easy as using a dryer--low energy for me as well as for the power plant.
In addition to saving energy, line drying has lots of other advantages. It can actually work better than a dryer for busy people, because you don't have to worry about being around when the dryer finishes to avoid clothes wrinkling. Clothes can last longer because they don't get overheated--this particularly helps preserve elastic. And rather than using detergents whose chemical scents try to mimic the fresh smell (or lack thereof) of line-dried clothes, you can have the real thing!
For more about the advantages of line drying, check out Project Laundry List, a non-profit dedicated to promoting simple ways of saving energy--such as line drying.
In this instructable, I'll describe strategies and equipment for hanging different kinds of clothes with minimum work, discuss setting up a clothesline (choosing a location, etc.), and finally describe options for minimizing dryer energy use if you do use a dryer. An appendix explains the small effect that drying clothes indoors can have on heating or air-conditioning energy use.
*For more on appliance energy see this summary; dryer energy use is typically 900 to 1000 kWh per year for an electric dryer.
