If your approach to saving energy with home lighting is limited to shutting off the switch as you leave a room, you’ve made a good start. But there’s much more you can do to help the environment and your electric bill.
If high-tech lighting isn’t something you are ready to consider just yet, adding simple dimmers to your current incandescent lighting scheme can also yield significant energy savings. For example an incandescent bulb dimmed by 10 percent, consumes 10 percent less energy than one on “full” light, and the bulb will last twice as long. Similarly, a bulb dimmed by 25 percent uses 20 percent less energy, and the bulb will last four times longer. Finally, a bulb dimmed by 50 percent uses 40 percent less electricity, and the bulb will last 20 times longer.
