It is not the prettiest of replies, but what I'm doing to be green lately, especially because California's water reserve is down 50%, is... only flushing the toilet every two or three times it is used. Also, lathering up and shaving in shower with water off, only turning on the water to rinse.
Baronwasteland, good going, and see it did pay off for your pocket too. I xeroscaped both front and back yard, its looks good and I did not even have sprinklers on last summer and all the plantings lived and grew. Got $500 rebate.
I installed a rain barrel, switched to CFL's, removed all my grass and planted a sustainable, climate appropriate garden that will keep rainfall in my yard instead of the storm drains. I also put in water saving fixtures throughout the house.
My water company gave me a rebate of $1 per sq. ft for turf removal. My rebate came to about $950.
I have a motor running outside and have used toggles that time to motor on and off and am experimenting on how few hours I can run it a day and still keep the function going. I saved $50 in the first month I tried this. So proving good environmental practices can also be good for your wallet. Tell me what you are doing group members.
