Remember clotheslines? Though we do have gas clothes dryers we also have plenty of clothesline space around each residential area. Some of us would never use a dryer.
Lighting. We primarily use compact flourescent bulbs, efficient strip flourescents, and some LED lights. We minimize indoor and outdoor night lighting. We make a conscious effort to turn down and turn off lights not in use.
Appliances. We avoid wasteful duplication by co-owning appliances. Few things we own sit around idle for lack of use. We use high-efficiency appliances in some cases.
