Light Nazi

Thanks to the Wife for stepping in during my absentia. I have recently developed a habit that is disturbing to me; I roam from room to room shutting off lights left on by the kids. Even worse, I am talking to no one in particular while I am doing this about conserving electricity, being wasteful, etc. My irritation rises when I have to go up or down stairs to do this. I have become the Light Nazi. Does anyone now of a 12 step program for this?
