Clean Coal

Much of America’s coal is mined by blowing the tops off of entire mountains and then dumping the rubble in streams and valleys. Not clean.

We know coal is dirty at the stack, and right now CCS technology is not being used to handle GHG emissions. Not clean.

The coal lifecycle doesn’t end at the smokestacks. Even after coal is burned, we’re left with billions of tons of coal ash and liquid coal slurry/sludge that must be stored and disposed of all across the country. The stuff is toxic, containing elevated levels of heavy metals like mercury and arsenic. Not clean.

For information on the threats that coal slurries pose, see this New York Times story from 2008. You can also read articles from major American newspapers on coal mining by mountain top removal here.
