Over the last week I’ve done a couple radio interviews related to my op-ed in the Detroit News, “U.S. must move beyond Earth Day slogans.”

Thanks to The Bill Meyer Show out of Medford, Oregon, who had me on in the morning last Thursday.

And thanks also to The Paul Edwards Program for having me on yesterday. I spoke with Paul at some length about plications of owning Compact Fluorescent Lightbulbs (CFLs). In the course of the interview (which you can listen to here), I referenced a couple webpages that I’ll pass along.

The first is 18Seconds.org, hosted by Yahoo!, at which you can track the sales of CFLs in your state or locality. Michigan has bought over 1.2 million CFLs since the beginning of 2007.

There is some information on the mercury in CFLs fairly deep into the “Why Switch?” section. Here’s a taste of the copy: “All fluorescent lights contain trace amounts of mercury. But don’t worry — there is far less mercury in CFLs than in thermometers or old thermostats. Plus, using these bulbs helps

prevent mercury from being released into the air from coal-powered power plants. When they burn out years down the road, recycle them.”

But here’s a second piece I talked about that might take issue with those claims: “The CFL mercury nightmare,” by Steven Milloy of . Milloy describes the experience of Brandy Bridges of Ellsworth, Maine, who faced a $2,000 clean-up bill when she accidentally broke a CFL, exposing mercury in her daughter’s bedroom.

Governments and corporations are engaging in huge campaigns to push the use of CFLs. The Home Depot gave away 1 million CFLs in an Earth Day promotion, and Wal-Mart is advocating them heavily. Check out this promotional video, “Energy Makeover,” from In Front with Wal-Mart, pany’s newest webcast program.

If the mercury in these CFLs, almost universally acknowledged to be a harmful environmental hazard, turns out to have serious health panies like Wal-Mart and The Home Depot could be opening themselves up to litigation. They may need to attach some sort of warning label (hopefully not a useless one that would win this contest).
