The renewable energy tax incentives will come up for a vote again soon in Washington, and a group of investors/activists will work the phones tomorrow to try to get a few key lawmakers to support incentives once again. And they want your help. The organization, a Facebook group called Renew Solar and Wind Incentives Now, is asking members and anyone else to call up the offices of three U.S. Senators--Chuck Grassley of Iowa, Richard Lugar of Indiana, and Elizabeth Dole of North Carolina-- and Congressman Steny Hoyer of Maryland and express their support for the tax incentives. The organization is not targeting die-hard opponents, explained Josh Becker, one of the organizers and a San Francisco-based venture capitalist. Instead, these are lawmakers that have supported incentives in the past and thus may do so again. Here are the numbers if you have some free time for calls tomorrow:

Senator Chuck Grassley (IA, R): (202) 224-3744
o Chief of Staff: David Young

Senator Richard Lugar (IN, R): (202) 224-4814
o Chief of Staff: Marty Morris

Senator Elizabeth Dole (NC, R): (202) 224-6342
o Chief of Staff: Greg Gross

Congressman Steny Hoyer (MD, D): (202) 225-4131
o Chief of Staff: Bill Cable
