Des Moines Register: A new report from the American Wind Energy Association says wind is now the largest single source of electricity in Iowa. According to the trade association’s Wind Powers America 2019 Annual Report, Iowa is now generating more than 10,000 megawatts of wind energy, accounting for more than 40% of the state’s electricity. Wind became the leading source of electricity in both Iowa and Kansas this year, making them the first states to reach that benchmark. Previously, coal-fired power generation had been Iowa’s main source of electricity.
