Chicago coal plants officially shut down

August 31, 2012 (CHICAGO)

Fisk and it sister plant, Crawford, were the last coal plants in the U.S. still in operation within the city limits.

About 1 million homes received power that was produced at the plant.

Their closings mark the elimination of the city's two biggest industrial sources of carbon dioxide emissions.

The plant's owner decided to close, instead of upgrading emissions control technology in order to meet new environmental regulations.
