Why should everyone change the Lightbulbs at home..


We spend much energy daily for light, even when we really don't need it! So thats why we should replace the lightbulbs with compact fluorescent ones. It costs three to five times as much as conventional bilb, but it burns 75% less energy and last years longer. So in the end we can actually have long term profit. A fact : If every U.S. home bought one compact fluorescent bulb the effect on greenhouse gases would be equivalent to taking 2 million cars off the road. Also new technology is on the door. LEDS or light-emitting diodes should do the job even better...
