From the The New York Times:
As the Senate prepares to tackle global warming, the nation’s energy producers, once united, are battling one another over policy decisions worth hundreds of billions of dollars in coming decades.
Producers of natural gas are battling their erstwhile allies, the oil companies. Electrical utilities are fighting among themselves over the use of coal versus wind power or other renewable energy. Coal companies are battling natural gas firms over which should be used to produce electricity. And the renewable power industry is elbowing for advantage against all of them.
