WASHINGTON (AP) — Energy Secretary Ernest 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 some coal-state Democrats that the president's climate plan would cripple the coal industry.

Moniz said Thursday that the administration plans to offer up to $8 billion in loan guarantees for technologies that can keep carbon dioxide produced by power plants from being released into the atmosphere. Several "carbon capture" demonstration projects are now underway, and Moniz said he expects them to be completed by the end of the decade.

He also said the administration would move more aggressively to make factories and appliances more energy efficient.
