Electric utility giant Duke Energy has quit the American Coalition for Clean Coal Electricity (ACCCE) because of the coal group’s unethical opposition to President Obama’s clean energy reform agenda.

For the last few years, Duke has been one of the most prominent industry voices calling for the regulation of industrial global warming pollution, but has also supported the efforts of various right-wing lobbying groups to prevent such action. ACCCE, in addition to promoting “clean coal” Christmas carols, employs right-wing public relations firms to paint the American Clean Energy and Security Act as a job-killing energy tax through whatever means necessary — even blatant forgery. According to the National Journal, Duke has finally recognized that the time has come to choose energy reform over old pollution:

Duke Energy left the American Coalition for Clean Coal Energy on Tuesday over differences with “influential member companies who will not support passing climate change legislation in 2009 or 2010,” the company said.

Duke Energy left the right-wing National Association of Manufacturers in May for similar reasons, but Duke’s CEO, Jim Rogers, still sits on the board of the U.S. Chamber of Commerce — alongside right-wing climate deniers Don Blankenship, Harry Alford, and George Argyros — which is spending tens of millions of dollars to kill clean energy jobs.

Members of business coalitions like the U.S. Climate Action Partnership (USCAP) and Business for Innovative Climate & Energy Policy (BICEP) have advocated for the establishment of a mandatory carbon market (“cap and trade”) to promote investment in clean energy while reducing global warming polution. In the meantime, business coalitions like the National Association of Manufacturers, ACCCE, the U.S. Chamber of Commerce, and the American Petroleum Institute (API) are running Astroturf campaigns to kill clean energy legislation.

However, Duke is not the only company that has been playing both sides of the field:
