Washington, D.C. — The wind power industry’s growth will slow sharply from last year’s levels under the usage mandates for renewable power being considered in Congress, industry officials say.

A bill approved by a House committee last month and another under consideration in the Senate would require utilities to get a certain percentage of their power from renewable sources starting in 2012, but the targets are well below what the wind power industry wanted.

The Senate version would start at 3 percent in 2012 while the House bill would begin at 6 percent, and both could be lowered through energy efficiency measures.

Iowa Gov. Chet Culver joined industry representatives Thursday in meeting with House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid, D-Nev., to urge them to enact higher mandates. “The number does matter,” Culver said later.
