Auto dealer Lem Rachels owns a wind turbine that federal money for clean energy helped buy. What Rachels lacks at his Shelby, N.C., business is wind. His 35-foot tower turns infrequently, sending scant green power into the grid. "It's probably about as bad a location as you can get for wind," Rachels said of his spot, near the South Carolina line. "If you were hunting out a wind location, this is not it." The business owner is among the hundreds of small companies that since last year have installed renewable power systems and recouped part of their costs through a program launched by the stimulus bill. Aimed at creating jobs and growing the green energy economy, the effort gives grants equaling as much as 30 percent of a project's cost for solar, wind and other renewable energy developments. Those awards come in place of tax credits companies could otherwise claim.
