IOWA CITY -- The Iowa Utilities Board chairwoman is taking the unusual, perhaps illegal, step of withholding funding from the state's renewable energy research center until its leaders satisfy her questions about its programs and finances.

The move by Geri Huser might violate a law that requires the funding to be appropriated to the Iowa Energy Center at Iowa State University once it's collected by the utilities board. If the delay continues, the center might have to suspend its grant programs and lay off workers. The funding is usually transferred by mid-September.
