Coal Fired Power Plants

At a bend in the Ohio River, a bulky new device is being attached to a 30-year-old coal plant near the small town of New Haven, W.Va. The device is being housed in a building four stories tall and bigger than a football field. A 150-foot-tall exhaust stack -- so wide that it would take six adults with their arms fully stretched to reach around it -- will reach into the sky. And pipelines will run out of the building and into saline aquifers two miles underground. The entire contraption will start up as early as September.

Los Angeles Mayor Antonio Villaraigosa drew cheers from environmentalists just over two months ago when he issued a new political promise: eliminating coal from the Department of Water and Power's fuel mix by 2020. Instead of waiting a decade to see if that promise comes true, a Sacramento-based advocacy group decided to stage a publicity campaign thanking the mayor. It bought advertising space on city bus kiosks showing a smiling picture of Villaraigosa and the word "Successful."
