Meanwhile, powerful environmental group the Sierra Club is targeting lawmakers returning to work with a month-long campaign in a key underground station near Congress.
The advertisements depict wind blue-collar workers and have one of two taglines aimed at a polarised legislature: Wind Power is Hard at Work; It’s Time for Congress to Do the Same; or Wind Power Makes Clean Energy, Good Jobs, and a Better Future. Don’t Blow It.

Congress is expected to act on the PTC during the ‘lame duck’ session, starting today and ending when lawmakers recess for Christmas and New Year.
