Going Green

Ok, seems like everyone is going "green" these days and I am no exception. My favorite part about going green is that it saves money!!! Are any of you doing anything to "go Green"? If so, what are you doing or what are your favorite ideas? I am air drying a lot of my clothes after i wash them, I have started using a lot of the energy saving light bulbs around the house, I recycle, I only turn a lamp on (that has an energy saving bulb) when i take my bath at night-which is quite relaxing by the way), and I am trying to run all my errands at once to save on gas. What are you doing?
