The tax-exempt Environmental Integrity Project in Washington, D.C.,
issued its annual list of the 50 dirtiest power plants in America. This
is illustrated by a photo showing steam "” water vapor "” escaping from a
cooling tower. Sigh.
I made this same point long ago, laughing at the huge number of air pollution reports that are illustrated with pictures of steam plumes. I also showed how photographers seemed to try to photograph the steam plumes at sunset, trying to turn them brown-looking to make it look like pollution. Unfortunately for pollution-report illustrators, power plants have been cleaned up enough that they don't really emit visible smoke plumes any more.
