- Change your incandescent lights to compact flourscent bulbs and remove all incandescent lights (except those you need for formal rooms with lamps).
- Change your flourescent tubes from T-12 to T-8. T-8 tubes use 30% less power but put out as much or more light as T-12 tubes.
- Install motion sensors which turn on lights when people walk into a room or down a hallway. While these motion sensors do cost to install, they will pay for themselves within a year or two.
- If you need to phase in the motion sensors due to the cost of installation, start with hallways, then go to closets and bathroooms (where people frequently forget to turn off lights), and then go to classrooms and offices.
