If you drive across Iowa, you’ll probably notice two things aside from the many farms: Trump signs and wind turbines.

Iowa is Trump country. While the state was once considered politically purple, it decisively supported President Donald Trump in 2016, in 2020, and in 2024, when Trump won in 94 of Iowa’s 99 counties. Iowa’s governor and two senators are also Republicans, and, after some early friction, have fallen in line with Trump.

Iowa is also a wind energy powerhouse. A remarkable 59 percent of the state’s energy in 2023 came from wind turbines, a larger share than any other state in the country. Texas is the only state that produces more wind energy than Iowa, though wind power makes up a much smaller portion of the Lone Star State’s energy mix. Wind turbines are now so common in Iowa that they appear on the state’s regular license plates.

At face value, wind energy and Trump don’t mix. Many of his supporters downplay or disregard climate science showing that fossil fuels are warming the planet far faster than it would naturally — a key fact underlying the value of wind energy and other power sources that don’t have significant carbon emissions. In some cases, Trump supporters, including Robert F. Kennedy Jr., also help elevate unproven claims that offshore wind turbines are killing whales.

Trump himself, meanwhile, is the most anti-wind-energy president in history. He’s been bad-mouthing wind power for over a decade, often relying on similarly spurious claims. “We’re not going to do the wind thing,” Trump said in a speech on Inauguration Day. “Big, ugly wind mills. They ruin your neighborhood.” And Trump has already made policy moves intended to slow growth in the sector — causing some developers to halt or totally abandon projects.

On one hand, Iowa is a test case for the staying power of renewable energy. Wind farms have expanded in the state not because of climate concerns but because of economics. Wind energy is cheap in Iowa.

But Iowa also highlights an important disconnect that exists across the country — between the anti-climate, “drill, baby, drill” rhetoric that helped get Trump elected and the reality facing much of his base living in states that benefit from renewable energy. The economics of wind energy are incredibly strong, experts told me, so the industry won’t just disappear. But Trump’s energy policies, if successful, could have harmful consequences for Republican strongholds like Iowa. A question now is if conservatives who rely on wind energy push back, will Trump soften his anti-wind stance?

How wind took over Iowa, a Republican stronghold

If you want to learn about wind energy in Iowa, the person to talk to is Tom Wind. (Yes, his name is literally Tom Wind, and yes, people point it out a lot to him.) He’s a crop farmer and electrical engineer in Iowa who’s been working in the sector — first at a utility, then as a consultant, and now as a wind-farm manager — for decades.

There are several reasons for Iowa’s ascendency to wind dominance, Wind told me. The simplest reason is that Iowa is windy. And while some Great Plains states like Nebraska and Kansas are technically windier, Iowa is closer to big population centers, like Chicago, that need lots of power.

Iowa was also quick to adopt policies that benefited wind and other renewables. In fact, Iowa was the first state in the country to establish what’s called a renewable portfolio standard (RPS), in 1983. It required the state’s........
