Eight of Colorado’s nine members of Congress are supporting a proposal to extend a federal tax break for companies working to produce wind energy — a proposal that stalled in the Senate on Tuesday.

The tax break is due to expire at the end of the year, and supporters say they’ll keep trying to find a way to extend it.

Colorado Sen. Michael Bennet, a Democrat, had sponsored the amendment that was defeated in the Senate Tuesday morning on a mostly party-line 49-49 vote.

Colorado, Bennet said, stands “to suffer a huge economic blow if Congress can’t get its act together and extend this critical tax credit.

“With thousands of high-quality jobs at stake across our state and the entire country, we need to provide certainty for this industry, so we do not derail its current growth.”
