Sen. Chuck Grassley is the author of the wind energy tax credit enacted in 1992 and has continued to support renewable energy tax credits since then. Sen. Grassley was awarded Dr. Harold D. Prior “Friend of Iowa Wind Energy in 2015. Upon receiving the award he was quoted as saying: “I’m honored to receive this award. In Iowa, wind produces 28 percent of the state’s electricity, ranking third in the United States. The industry supports thousands of jobs and generates billions of dollars in investment across Iowa and the nation. It’s a non-polluting, renewable resource. Wind energy makes sense for America’s future, and I’ll continue to fight for it through my position in the U.S. Senate." <ref>[http://www.grassley.senate.gov/news/news-releases/grassley-named-friend-iowa-wind-energy]</ref>
