One of Iowa's U.S. Senators says he's surprised at how far the state's wind energy production has come. Iowa continues to lead the nation in wind energy, and Republican Sen. Chuck Grassley was among its early backers. This week the US Department of Energy reported Iowa generates more than 30 percent of its power from wind, the highest percentage in the country. Grassley says back in 1992 when he pushed for tax incentives for wind energy, he didn't expect it would get this big.
"I'm glad it is," Grassley says, "but I'm just telling you I didn't foresee that."
