For a proper analysis you'd have to figure out how much mercury the power plants emit per KWh. Then compare that to how many kWh's you save using the CFLs over incandescent bulbs.In 1999 US coal burning power plants polluted the air with 48.7 tonnes of Mercury. 1 CFL contains about 5 milligrams of Mercury, or 0.000000005 tonnes. So people would need to throw away 9.74 billion CFLs per year to match yearly Mercury output of all coal fired plants in USA in 1999. Any decent quality CFL will last at least 5 years, often longer that that. So that means that 48.7 billion CFL's can be in circulation in USA and not exceed yearly Mercury pollution of coal burning power plants in 1999. This comes out to 159 CFLs per person in USA thrown away every 5 years. I have 9 CFLs, had them for at least 4 years already and none are yet to fail. I plan on storing all of my burned out CFLs and when i collect enough, I will drop them off at a recycling center somewhere. Judging from their failure rate, i will only have to do that once in my life.
Let's say I have a 26-watt CFL that lasts for 4000 hours... That would be about 6 100-watt incandescent bulb lifetimes, adding up to a grand total of 400 kWh of electricity. The CFL would only use 104 kWh over those 4000 hours, saving 296 kWh of electricity. So burning 4000 hours of incandescent on Sunbury electricity releases 31.6 mg of mercury into the environment. Burning 4000 hours of CFL on Sunbury electricity releases 8.2 mg of mercury into the environment. If the bulb is broken and its mercury released then it is 14 mg (assuming 5 mg Hg in the CFL, which is about the norm).
It has long been the custom of the people to take action, to take up arms as it were, when the corporations/governing bodies fail too, even though it may be an unfair burden to impose upon the individual, every major sociological/commercially viable change begins with baby steps, one at a time...unfortunately.In 1999 US coal burning power plants polluted the air with 48.7 tonnes of Mercury. 1 CFL contains about 5 milligrams of Mercury, or 0.000000005 tonnes.

California Refund Value
Consumers pay CRV (California Refund Value) when they purchase beverages from a retailer, which is refunded when they redeem the containers at a recycling center....
Traditional bulbs are being phased out gradually to allow manufactures to adapt. Europe plans to phase out 60 watt clear lights from September 2011.
A Government spokesman said: 'There are many myths around low-energy bulbs. People don't always realise they have improved beyond recognition.'
