Moniz says coal will continue to play a role in meeting America's energy needs even as the Obama administration seeks to reduce carbon emissions and combat global warming. In an interview with The Associated Press, Moniz refuted claims by Republicans and even some coal-state Democrats that the president's climate plan would cripple the coal industry.
