If you are concerned about how much energy you are using, but are forgetful and need some encouragement, this little switch will give you a visual representation of how much energy you are using. The switch lights up only a little when you’re not using much energy and it shines brighter when you’re wasting too much.
What with energy being invisible, it’s easy to waste more then you intend to. So a visual reminder is just the thing. Not many other details on this one for the moment. Like how much of your house this will take care of, etc. It might be good if it were vocal though, “Turn off some lights you wasteful pig. What did you buy me for if you aren’t going to listen to me.” Nagging always gets things done after all, as any married person knows.
