RESPONSE TO CONCERNS ABOUT COMPACT FLUORESCENT BULBS
MERCURY IN COMPACT FLUORESCENT BULBS
It is crucial that people convert to compact fluorescent bulbs for the following
reasons:
1. There will be less mercury contamination if people use compact fluorescent
bulbs (see below).
2. It is critical that we reduce our carbon emissions to help prevent
catastrophic climate change
3. As the use of compact fluorescent bulbs becomes more common place, local
governments will be more likely start providing recycling or special disposal
for them. Right now, not a lot are available for recycling, partly because they
last so long and their use has only recently become widespread.
The Environmental Protection Agency agrees that use of compact fluorescent
bulbs causes less mercury contamination than the use of regular bulbs. The
environmental protection agency states that "CFLs present an opportunity to
prevent mercury from entering our air, where it most affects our health."
We'll quote the pertinent part of the Union of Concerned Scientists spring
newsletter ("earthwise") which sums things up: "One drawback to
CFLs is that they use a small amount of mercury (about five milligrams) to
generate light. However, this pales in comparison with the amount produced by
the largest source of U.S. mercury emissions: the coal-burning power plants that
produce 52 percent of our nation's power. For example, the average existing
coal-fired power plant emits 13.6 milligrams of mercury to power a typical
incandescent bulb, but only 3.3 milligrams for a CFL. The reduction in mercury
emissions achieved by burning less coal exceeds the five milligrams of mercury
inside a CFL. And unlike coal-fired power plants, which emit mercury
directly into the atmosphere (where it most affects our health), the mercury in
CFLs can be contained as long as you dispose of them properly. "
Compact fluorescent bulbs should be recycled or brought to your local Household
Hazardous Waste Collection Site if they accept them, but even if they are
thrown in the trash, it is still better than using regular light bulbs. If
your local sites do not accept CFL's the Environmental Protection Agency
recommends that you "seal the CFL in a plastic bag and place with your
regular trash."
CONCERN ABOUT THE WAY THE LIGHT LOOKS
Some people do not like the light of certain CFL bulbs. Like regular bulbs
they vary in brightness and color quality. The light varies a lot by brand
(but not by price). Check out your friend's lights to find a brand and
color tone you like.
