If our math is correct... the CFL will cause 14mg of mercury pollution over its lifetime as compared to 42mg of mercury pollution for an equivalent number of incandescent bulbs It would appear it is not correct.
And even this is over stated. In both examples the calculation is based on 100% coal power generation. Coal provides less than half the electrical power in the US. When using realistic numbers for American power generation, the CFL causes more mercury pollution.

What is unstated is that the mercury per ton of coal is depenedent on coal location and mine source. Like high sulfur and low sulfur coal, the amount of mercury varies according to what the mine source is.

The articles assumption that all electricity came from coal was clearly wrong. Thanks for taking an independent look!
