When you pay 65 cents a kilowatt hour for electricity, something as simple as swapping an old-fashioned incandescent light bulb for an LEDLight-emitting diode. Illumination technology that produces light by running electrical current through a semiconductor diode. LED lamps are much longer lasting and much more energy efficient than incandescent lamps; unlike fluorescent lamps, LED lamps do not contain mercury and can be readily dimmed. lamp can add up to big savings.
