One of the easiest and cheapest means of reducing energy usage and reducing your "carbon footprint" is to make the lighting in your home and/or business more efficient. A compact florescent light bulb (CFL) installed in place of an incandescent bulb will save about $30 over the course of its lifetime and pay for itself within six months. Using 75 percent less energy, CFls lasts about 10 times longer than incandescent bulbs. Also, LED (light emitting diode), a semiconductor device that converts electricity into light, has grown increasingly popular as technology has made it viable for both industrial and residential applications.
