Two House Democrats want a vote on an extension of expiring wind energy tax credits when lawmakers battle over GOP legislation that would thwart federal rules that Republicans call anti-coal.

The proposed amendments are more evidence that Democrats are making an extension of the soon-to-expire credit — which the wind industry calls vital to financing new projects — a major political priority.

Reps. Earl Blumenauer (D-Ore.) and Leonard Boswell (D-Iowa) have filed separate amendments that would extend the wind credit, which is slated to end this year, through the end of 2016.

Their plans would also extend credits for other renewable sources that are currently slated to expire at the end of 2013. The House bill comes to the floor later this week, with a final vote expected Friday.
