Does someone in your home always leave the light on in his or her bedroom? Or maybe it's the bathroom where the light and fan work overtime when it's not necessary. In many homes the basement light burns for hours until someone remembers to turn it off.

You can stop wasting energy by replacing a standard light or light and fan switch with an occupancy sensor that turns a light on automatically when you enter and off when you leave a room. The device comes in single and double switches with or without a nightlight, a feature especially useful in a bathroom or bedroom.

An electrician will replace a single switch sensor with a nightlight for $105, which includes labor and material. You can buy the device for $40 and do it yourself if you have electrical tools and experience using them. You'll be rewarded with a 62 percent saving for your effort.

The average price to install an occupancy sensor noted above is cost data to compare a contractor’s estimate with doing it yourself. Tweak the data by adding your ZIP Code to find a local cost.
