The Washington Post just moments ago reported that the Senate failed again to extend vital Federal Tax Incentives for the green energy sector. Federal ITC measures will expire at the end of the year without further action.

Washington Post: By H. JOSEF HEBERT The Associated Press Tuesday, June 10, 2008; 12:42 PM:

Democrats failed to get Republican support for a proposal to extend tax breaks for wind, solar and other alternative energy development, and for the promotion of energy efficiency and conservation. The tax breaks have either expired or are scheduled to end this year.

The tax provisions were included in a broader $50 billion tax measure blocked by a GOP filibuster threat. A vote to take up the measure was 50-44, short of the 60 votes needed.

California Solar Energy Industries responded immediately. From their email:

Regrettably, on a vote of 50-44 the U.S.Senate failed to invoke cloture on HR 6049, the bill that proposes extension of the Federal tax credits for commercial and residential customers. This occurred about 15 minutes ago.
SEIA will undoubtedly be working hard on a strategy for achieving enactment of an extension – we’ll keep you posted on the next steps and share information as it becomes available.
