Last summer, clean energy advocates were confident that the U.S. Congress would pass a comprehensive energy and climate bill by the time the Copenhagen conference rolled around. Now, as energy issues slip further down the policy priority list in the wake of that failed meeting, advocates are left wondering if the U.S. will see any significant piece of clean energy legislation in 2010.

"Sometimes you have to separate the climate issues and the renewables issues...They are both extremely important...but I sometimes have to pinch myself when I see where [the renewable energy industry] has come. It's on a trajectory that I don't think can be stopped." -- Scott Sklar, President of the Stella Group, Ltd.
