Wind may be under siege again on Capitol Hill. A proposed repeal of the wind production tax credit, which crossed a crucial hurdle on September 20 when it passed the powerful House of Representatives Ways and Means Committee, could mean wind projects in the US lose at least $120 million between 1996 and 2000. The committee chairman, Bill Archer of Texas, claims axing the tax credit will save $400 million -- an exaggeration according to the American Wind Energy Association (AWEA) which says it is based on an impossibly high production figure for wind and closed loop biomass. "This plan is unfair and will kill all wind development," says AWEA's tax expert Ed Ing. The proposal has to be debated by the full house membership and the US Senate. Whether is goes ahead or not should be clear by mid to late October, says AWEA.
