Wind energy is now the largest single source of electricity in Iowa, according to a press release from the American Wind Energy Association. Iowa generated at least 10,000 megawatts of wind energy, which accounted for at least 40% of Iowa’s total electricity in 2019. 

In 2018, coal was the primary fuel for Iowa’s electric grid and accounted for 45% of energy production in the state but was declining according to The U.S. Energy Information Administration (EIA). The 2018 report showed that Iowa had the second highest share of wind turbines for any state, where 4,700 wind turbines produced 34% of the state’s total electricity.

Coal produced 33% of total U.S energy related CO2 emissions in 2018 according to an EIA report. Wind energy does not produce emissions but does have issues related to noise production according to the Union of Concerned Scientists. These noise issues do not affect health and can be mitigated by technological advances and community planning. 

The rising use of wind and solar energy in our power grid reduces cost, reduces heat trapping emissions that contribute to Earth’s warming climate and improves public health, according to the Union of Concerned Scientists
