In 2015, 11 states generated at least 10% of their total electricity from wind. As recently as 2010, only three states had at least a 10% wind share. Iowa had the largest wind generation share, at 31.3%, and South Dakota (25.5%) and Kansas (23.9%) had wind generation shares higher than 20%. Two additional states, Texas and New Mexico, are on track to surpass a 10% wind generation share in 2016, based on data through July.
