Christmas Lights

I’m thinking this could be green but maybe to some not. For Christmas I have almost all my lights on a timer. They come on right before I get home (that’s nice) and they go off before I go to bed. How can this be green? Well many people forget to turn them off, especially those outside. I no longer have to think of that. I have purchased enough timers over the years to cover all areas. They get packed away with the lights. I also do not use lamps or lights other than Christmas most of the season. My husband doesn’t care for this type of lighting all the time but Santa likes it!
