Old Coal
FILE - In this April 25, 2010 file photo, President Barack Obama returns to the White House in Washington after attending a memorial for coal miners who died in an explosion in West Virginia. Utilities across the United States are building dozens of old-style coal plants that will cement the industry's standing as the largest industrial source of climate-changing gases for years to come. The construction wave stretches from Arizona to Illinois and South Carolina to Washington, and comes despite growing public wariness over the high environmental and social costs of fossil fuels, demonstrated by tragic mine disasters in West Virginia, the Gulf oil spill and wars in the Middle East.
