Everyone knows that switching out your light bulbs to CFL saves money, but many people are concerned about the mercury in them.
According to John Balbus, M.D., Chief Health Officer at Environmental Defense, CFLs contain less mercury than was in the old-fashioned mercury thermometers. And even broken, he says the exposure rate is about equivalent to a "can or two" of tuna fish.
In addition, when compared to the total life cycle of incandescent bulbs, from production to the amount of energy from a coal-burning plant needed to power the bulb over its life, CFLs are responsible for far less mercury in our environment. According to Popular Mechanics:
But even if there is less mercury used in the total production, the CFLs do have a small amount mercury inside each bulb. Clearly, we want to avoid throwing spent bulbs into the regular garbage where they can easily break and end up in our landfills. Yet it can be inconvenient to collect the used bulbs for delivery to Miami-Dade’s Home Chemical disposal sites.

Approximately 0.0234 mg of mercury—plus carbon dioxide, sulfur dioxide and nitrogen oxide—releases into the air per 1 kwh of electricity that a coal-fired power plant generates. Over the 7500-hour average range of one CFL, then, a plant will emit 13.16 mg of mercury to sustain a 75-watt incandescent bulb but only 3.51 mg of mercury to sustain a 20-watt CFL (the lightning equivalent of a 75-watt traditional bulb). Even if the mercury contained in a CFL was directly released into the atmosphere, an incandescent would still contribute 4.65 more milligrams of mercury into the environment over its lifetime.

This is why Ikea and Home Depot have set up light bulb recycle programs in their stores. Home Depot just rolled out their program nationally last month. From their press release:
The Home Depot®, the world's largest home improvement retailer, today expanded its long-term commitment to the environment and sustainability by launching a national in-store, consumer compact fluorescent light (CFL) bulb recycling program at all 1,973 The Home Depot locations. This free service is the first such offering made so widely available by a retailer in the United States andIKEA, the popular home furnishings store, also offers free recycling of your spent CFLs:

decisions from purchase to disposal.
