Gov. Terry Branstad says Iowa has the potential to jump above 40 percent in the next five years.
In a report released Monday the association said wind produced more than 190 million megawatt-hours of power in the U.S. last year, enough electricity for about 17.5 million typical homes.
The goal is for the U.S. to derive 20 percent of its electricity by 2030. The nation was at 4.7 percent from wind last year.
