I am a lights Nazi in my house. I also always turn off lights at work that people leave on all the time.
I told this story before but I made a flyer and put it up at work asking people to not sit out in there cars with them running and to instead utilize our awesome break room.
I never run my vehicle unless I need to. I ride my bike and walk to the store. I use public transportation. The last car I bought was hybrid that gets about 50 miles to the gallon. I recycle religiously. I utilize the heat from the sun in the winter as much as possible and close the blinds in the summer to use less energy for cooling (also keep my thermostat at 75 in the summer which is hotter than most).
I only have one TV in my house. I pick up trash that others leave all over the place. When I need hot water instead of running water down the drain as I wait for it to get hot, I instead collect it in a big pitcher to use to water the plants and pets etc.
I do as much as I reasonably can (most of that stuff is really easy) to make the world a better place.
