The latest Iowa Climate Statement signed by more than 200 scientists and researchers at Iowa colleges and universities says the state needs to invest more in solar power. Retired Iowa State University climate scientist Gene Takle says when wind is paired with solar, they tend to make up for each other’s weaknesses.

Around 60 percent of electricity generated in Iowa comes from wind. University of Iowa environmental health professor Peter Thorne says solar could potentially overtake wind.

Several large-scale solar projects are under development, including a 200 mega-watt solar farm in Linn County at the former Duane Arnold nuclear plant. Iowa’s electric wind production is higher share than any other state, but Iowa solar energy capacity is well below the national average.
