Energy-consumption, rising gasoline costs and electric bills, greenhouse-gas emission, dependence on coal and oil, global warming. I know, these are the hot problems of the world. You can help the situation simply by replacing your ordinary bulb by CFL.



The compact fluorescent light (CFL) bulb pricing only $3, a twisty bulb of white glass is appealing in looks and energy saver as well. It consumes 75% to 80% less electricity than ordinary bulb. It means if every one of 110m American household bought one CFL bulb instead of ordinary 60W bulb, the conserved energy would be sufficient to light-up a 1.5 million-populace city.
