Energy-Saving Light Bulbs not Really Green

Although an energy-saving lamp can save 60 percent to 80 percent on electricity usage and has a much longer service lifespan than an incandescence bulb, it can pollute 1,000 liters of water and 300 cubic meter of air, the reported.

Due to costs and technological restraints, Chinese companies are incapable of producing non-mercury bulbs. 0.5mg mercury content in each bulb will poison 1,000 liters of water and further impact soil and crops.

"No matter whether it's buried or burnt, energy-saving bulbs will cause pollution to water and soil." said an official at the Hebei provincial environmental protection bureau.
