When I was a kid, my mom was always after me to turn off the lights after I left a room. I got to be pretty good, even nagging my friends when they left lights on. It wasn’t a global warming or environmental thing back then, it was to save money. Now that everyone in on an energy savings kick, I thought I’d offer a nag-free solution: motion-sensitive light switches. These have a light switch and a little curved plastic window. Behind the window sits a device to sense motion in the room. I have seen them in lots of offices and I’ve heard some states require them in commercial buildings.
These are great for walk-in closets, bathrooms, kid’s rooms and other places where people tend to leave on the lights. They’re good for real rooms, too, but don’t use them where you might unexpectedly fall asleep! If you have one in the living room and you fall asleep on the couch, the light will go out and you will have a nice comfortable night’s sleep on the couch. Oops.
You can pick these up at almost any hardware store. They are no different/difficult to install than a normal light switch.
