Huh? missinformation.  The USA consumes TEN TIMES the energy as china, and European(EU 27) consumes another 5 times.  And most of the USA energy comes form burning coal.  So blaming it on the Chinese is completely obfuscating the issue.

More missleading info.  The amount of mercury in a CFL is about equal to the amount of Mercury released into the environment from buring coal to power a home with incandescents per year.  But the CFL lasts 10 years!  And every place that sells them accepts them back for re-cycling.

"Very poor efficiency" is a meaningless subjecive term.  Yes the power supply in a CFL is only converting about 20% of the electricity to light, but that is 400% better than an incandescent wihch only produces 5% light at best!  Hence the 4-to-1 savings from using CFL's.
