I am posing this as a question because I really don't know the answers and am hoping to get both sides of the story here, as many of us would be categorized in the "green" column if we were to be queried. Are CFL (compact florescent lights) really any better for the environment considering they have a fair amount of mercury in them? I have tried to consider both sides. First, being much more energy efficient and second, having mercury as a component. If we all start using them, how much "more" mercury will we be adding to the dumps in several years as they start to die and need replacement. As well as the process of extracting mercury from ma earth? Is this just a trade off, one pollution vs. another or is there a distinct advantage? Just trying to figure it out.
