We use cold water for washing. We have solar power for our hot water. We have energy efficient lights in the house and only turn on the lights in the room we're in. Our outdoor lights are all motion sensitive so if you're not moving they go off (which can be spectacularly annoying at times). In Oz every toilet has to have a dual flush system so you only need to full flush to get rid of really nasty stuff. Our house has wooden floors so no need to use electricity with a vaccuum.
