Coal plants currently supply 32 percent of the nation’s electricity, and are the largest U.S. source of both sulfur dioxide and mercury as well as carbon dioxide linked to global warming.
For the twelve months ending in June 2012, United States' coal plants produced 1,563,298 gigawatt hours of electricity, or 38.4 percent of total U.S. electricity production.
Is it 32% or 38%?
