Lately, we have heard that the small amount of Mercury in CFLs could be an environmental problem. Well, that problem is solved.
The Home Depot will accept unbroken consumer compact fluorescent light bulbs (CFLs) at all locations. The services if free. Just turn in your CFLs to the clerk at the Returns desk.
If every American swapped one incandescent bulb for a CFL, it would save enough energy to light more than 3 million homes for one year, save more than $600 million in annual energy costs and prevent greenhouse gases equivalent to the emissions from 800,000 automobiles.
