Iowa now gets 57% of its electricity from in-state wind energy, and it does this consistently. Texas produces way more megawatts of wind energy than other states. No other state is even close. Yes, I know, this is completely the opposite of what most people think. But hey, there’s plentiful flat land and wind in those states. So, it makes economic sense too. Graphic from EIA.gov.
Iowa is a national leader in wind energy, producing the highest percentage of electricity produced by wind – over 57 percent (2022) – of any state. Iowa is the first state to generate more than 57 percent of its electricity with wind power. Iowa also ranks second nationally in the amount of wind energy installed with 12,219 MW (2021).
