You don’t have to outfit your home with pricey solar panels. These improvements can be done cheaply…or even for free!
Add a Motion Sensor
Add motion sensor to your outdoor lighting fixtures. One of these (around $20 each) turns off the light when nobody's present. The gizmos are great for the seldom-used areas of your home, like the basement and guest room.
