The project, 17 years in the making and spanning 1,500 acres, hasn’t sparked a whole lot of opposition despite its mammoth size. This might be because the turbines aren’t located near homes, but on privately owned cattle ranches and federal lands managed by the Bureau of Land Management. Aside from a few raised eyebrows and that one shocked couple, not many people in Rawlins seemed all that bothered. Then again, Rawlins doesn’t have too many folks to bother (population 8,203).

Wyoming was once this country’s coal-mining capital. Now, with the development of wind farms, it’s becoming a major player in clean energy, part of a significant energy transition aimed at reducing our reliance on fossil fuels.

Even so, Phil Anschutz, whose company is behind the Chokecherry and Sierra Madre wind farms, didn’t get into the green energy game just to save the climate. “We’re doing it to make money,” admits Anschutz, who got the bulk of his billion-dollar fortune from the oil industry. With California’s mandate to end its reliance on fossil fuels by 2045, he now sees a profitable opportunity, and he’s pulling Wyoming along for the ride.

Since 1988, Wyoming has been the country’s top coal-producing state, but its mining has declined steeply over the past 15 years, as has coal mining more generally in the United States where 40 percent of coal plants are set to be shuttered by 2030. In addition to the closed plants, the downturn in coal output has resulted largely from cheap natural gas prices and the influx of utility-scale renewable energy projects. Wyoming’s coal production peaked in 2008, churning out more than 466 million short tons. Today, its mines produce around 288 million short tons of coal, accounting for 40 percent of America’s total coal mining and supplying around 25 percent of its power generation. Coal plants are also responsible for more than 60 percent of carbon dioxide emissions from the country’s power sector. As far as the climate is concerned, that’s still way too much.

The good news is that the United States has witnessed a dramatic drop in daily coal use, down 62 percent since 2008, and few places have felt coal’s rapid decline more than Wyoming, where a green shift is distinctly afoot. Despite being one of the country’s most conservative states (71 percent of its voters backed Donald Trump this year), Wyoming is going all in on wind energy. In 2023, wind comprised 21 percent of Wyoming’s net energy generation, with 3,100 megawatts, or enough energy to power more than 2.5 million homes. That’s up from 9.4 percent in 2007.

On the surface, Wyoming’s transition from coal to wind is laudable and entirely necessary. When it comes to carbon emissions, coal is by far the nastiest of the fossil fuels. If climate chaos is to be mitigated in any way, coal will have to become a thing of the past and wind will provide a far cleaner alternative. Even so, wind energy has faced its fair share of pushback. A major criticism is that wind farms, like the one outside Rawlins, are blights on the landscape. Even if folks in Rawlins aren’t outraged by the huge wind farm on the outskirts of town, not everyone is on board with Wyoming’s wind rush.

“We don’t want to ruin where we live,” says Sue Jones, a Republican commissioner of Carbon County. “We can call it renewable, we can call it green, but green still has a downside. With wind, it’s visual. We don’t want to destroy one environment to save another.”

Energy from the Chokecherry and Sierra Madre wind farms will also reach California via a 732-mile transmission line known as the “TransWest Express,” which will feed solar and wind energy to parts of Arizona and Nevada as well. To be completed by 2029, the $3-billion line will travel through four states on public and private land and has been subject to approval by property owners, tribes, and state, federal, and local agencies. The TransWest Express passed the final review process in April 2023 and will become the most extensive interstate transmission line built in the United States in decades. As one might imagine, the infrastructure and land required to construct the TransWest Express will considerably impact local ecology. As for the Chokecherry and Sierra Madre wind farm, it might not encroach on residential neighborhoods, but it does risk destroying some of the best natural wildlife habitats in Wyoming.

Transmission towers connecting thick high-voltage power lines will stand 180 feet tall, slicing through prime sage-grouse, elk, and mule deer habitat and Colorado’s largest concentration of low-elevation wildlands. The TransWest Express will pass over rivers and streams, chop through forests, stretch over hills, and bulldoze its way through scenic valleys. Many believe this is just the price that must be paid to combat our warming climate and that the impact of the Chokecherry and Sierra Madre projects, and the TransWest Express will be nothing compared to what unmitigated climate chaos will otherwise reap. Some disagree, however, and wonder if such expansive wind farms are really the best we can come up with in the face of climate change.

“This question puts a fine point on the twin looming disasters that humanity has brought upon the Earth: the climate crisis and the biodiversity crisis,” argues Erik Molvar, a wildlife biologist and executive director of the Western Watersheds Project, a Hailey, Idaho-based environmental group. “The climate crisis and the biodiversity crisis are of equal importance to humans and every other species with which we share this globe, and it would be foolhardy to ignore either in pursuit of solutions for the other.”

Molver is onto something often overlooked in discussions and debates around our much-needed energy transition: What consequences will these massive renewable energy projects have on biodiversity and the wild creatures that depend on these lands for survival?

Biologists like Mike Lockhart, who worked for the US Fish and Wildlife Service (FWS) for more than 30 years, claim that these large wind farms are more than just an eyesore and will negatively affect wildlife in Wyoming. Raptors, eagles, passerines, bats, and various migrating birds frequently collide with the blades, which typically span 165 feet.

“Most of the [Wyoming wind energy] development is just going off like a rocket right now, and we already have eagles that are getting killed by wind turbines—a hell of a lot more than people really understand,” warns Lockhart, a highly respected expert on golden eagles.

In a recent conversation with Dustin Bleizeffer, a writer for WyoFile, Lockhart warned that wind energy development in Wyoming, in particular, is occurring at a higher rate than environmental assessments can keep up with, which means it could be having damning effects on wild animals. Places with consistent winds, as Lockhart explains, also happen to be prime wildlife habitats and most of the big wind farms in Wyoming are being built before we know enough about what their impact could be on bird populations.

In February 2024, FWS updated its permitting process under the Bald and Golden Eagle Protection Act, hoping it would help offset some of wind energy’s effects on eagles. The new rules, however, will still allow eagles to die. The new permits for wind turbines won’t even specify the number of eagles allowed to be killed and companies won’t, in fact, be out of compliance even if their wind turbines are responsible for injuring or killing significant numbers of them.

Teton Raptor Center Conservation Director Bryan Bedrosian believes that golden eagle populations in Wyoming are indeed on the decline as such projects only grow and habitats are destroyed—and the boom in wind energy, he adds, isn’t helping matters. “We have some of the best golden eagle populations in Wyoming, but it doesn’t mean the population is not at risk,” he says. “As we increase wind development across the U.S., that risk is increasing.”

It appears that a few politicians in Washington are listening. In October, California Representative Jared Huffman and Pennsylvania Representative Brian Fitzpatrick introduced a bipartisan bill updating the Migratory Bird Treaty Act of 1918. The legislation would authorize penalties of up to $10,000 per violation for harm to birds. Still, congressional staffers tell me it’s unlikely to pass, given the quiet lobbying efforts behind the scenes by a motley crew of oil, gas, and wind energy developers.

The Department of Energy projects that wind will generate an impressive 35 percent of the country’s electricity generation by 2050. If so, upwards of 5 million birds could be killed by wind turbines every year. In addition to golden eagles, the American Bird Conservancy notes that “Yellow-billed Cuckoos, Golden-winged Warblers, and Kirtland’s Warblers are particularly vulnerable. Wind energy poses special risks to endangered or threatened species such as Whooping Cranes and California Condors, since the loss of even a few individuals can have population-level effects.”

And bird kills aren’t the only problem either. The constant drone of the turbines can also impact migration patterns, and the larger the wind farm, the more habitat is likely to be wrecked. The key to reducing such horrors is to try to locate wind farms as far away from areas used as migratory corridors as possible. But as Lockhart points out, that’s easier said than done, as places with steady winds also tend to be environments that traveling birds utilize.

Even though onshore wind farms kill birds and can disrupt habitats, most scientists believe that wind energy must play a role in the world’s much-needed energy transition. Mark Z. Jacobson, author of No Miracles Needed and director of the Atmosphere/Energy Program at Stanford University, notes that the minimal carbon emissions in the life-cycle of onshore wind energy are only outmatched by the carbon footprint of rooftop solar. It would be extremely difficult, he points out, to curtail the world’s use of fossil fuels without embracing wind energy.

Scientists are, however, devising novel ways to reduce the collisions that cause such deaths. One method is to paint the blades of the wind turbines black to increase their visibility. A recent study showed that doing so instantly reduces bird fatalities by 70 percent.

Such possibilities are promising, but shouldn’t wind project creators also do as much as possible to site their energy projects as close to their consumers as they can? Should Wyoming really be supplying California with wind energy when that state already has plenty of windy options—in and around Los Angeles, for example, on thousands of acres of oil and brownfield sites that are quite suitable for wind or solar farms and don’t risk destroying animal habitats by constructing hundreds of miles of power lines?

Wind energy from Wyoming will not finally reach California until the end of the decade. As Phil Anschutz reminds us, it’s all about money, and land in Los Angeles, however battered and bruised, would still be a far cheaper and less destructive way to go than parceling out open space in Wyoming.

In that roadside cafe in Rawlins, the two workers paid their bill and left. I sat there quietly, wondering what that couple made of the revelation that the wind farm nearby wasn’t going to benefit them. Finally, nodding toward the men’s truck as it drove away, I asked, “What do you think of that?”

“Same old, same old,” the guy eventually replied. “Reminds me of the coal industry, the oil industry, you name it. The big city boys come and take our resources, and we end up having little to show for it.”

Shortly after lunch, I left Rawlins and made my way two hours north to the Pioneer Wind Farm near the little town of Glenrock that began operating in 2011. I pulled over to get some fresh air and stretch my legs. As I exited the car, I could hear the steady hum of turbines slicing through the air above me and I didn’t have to walk very far before I nearly stepped on a dead hawk in the early stages of decay. I had no way of knowing how the poor critter was killed, but it was hard to imagine that the hulking blade swirling overhead didn’t have something to do with it.
