We have replaced all of our lights which are not on dimmers, with CFL (compact flouresent lights) we also live on a well and septic, so we limit the amount of extra water usage. One interesting thing that I just watched on our local news station is that running the dishwasher actually uses less water than handwashing dishes. I have checked into a residential wind turbine also (I live on top of a mountain looking down the valley so we always have wind) but it is still really out of reach price wise ($4500-$15000) depending upon how much power you want to create. Solar is also still out of reach for me. As much as I would love to use these, until I can afford them, or they make them cheaper, there is just only so much you can do.
