I always wash in cold water and line dry my clothes - those are obvious and make a big difference, reducing the energy I use. I hang up my clothes if I've worn them briefly, so they air out and can be worn again.
What else can I do, that won't cost a huge amount?
I've been putting together some info on this at http://www.appropedia.org/Washing_and_drying_clothes - that's a wiki page, so anyone can edit. Any input appreciated!
