When farmer Trent Gerlach found out a solar farm would be built on the land he had long worked in northwestern Illinois, he was disappointed.

"As a farmer, seeing that land taken out of production is difficult, when you farmed it for many years, you've been stewards to that land, fertilized that land, taken care of it as if it was your own," he said.

Gerlach's family had been raising corn, soybeans and livestock since 1968, and like many farmers, they leased farmland in addition to working their own land. And when the owner of one of those leased parcels decided to work with Acciona Energia to help site its High Point wind and solar farm, Gerlach initially was not enthusiastic.

"The thought of taking productive farm ground out of production with solar panels was not, in my personal opinion, ideal," he said.

But Gerlach was determined to make the best of the situation.

Ultimately, that meant a win-win arrangement, where Acciona pays him to manage vegetation around the 100 MW array of solar panels that went online in early 2024. Gerlach does that with a herd of 500 sheep.

"We don't own the land, we don't get a say - that's landowners' rights, and I'm very pro that," Gerlach recounted. "In U.S. agriculture, the biggest thing that gets farmers in trouble is saying, 'that's how we've always done it so that's what we're going to do.' Renewable energy is probably not going anywhere, whether you're for or against it, it's coming, it's what's happening. As an agriculture producer, we're going to adapt with it."

A promising arrangement

Researchers around the country are exploring agrivoltaics, or co-locating solar generation with agriculture in a mutually beneficial way. Projects range from growing tomatoes in California to wild blueberries in Maine, with varying levels of success.

Acciona regional manager Kyle Charpie said that sheep grazing appears an especially promising form of agrivoltaics, and one that the company is likely to continue exploring globally. Solar operators need to keep vegetation controlled, and sheep are a more effective and ecological way to do it than mechanized mowing. Acciona has long had a sheep agrivoltaic operation in Portugal, Charpie noted, and two projects in Texas are underway.

"It's incredibly cost-effective - sheep don't break down like a tractor; if a tractor blows a belt, you've lost a whole day of cutting," he said. "These grasses grow wickedly fast, it's that constant presence of the sheep that's been super super effective. It aligns with our sustainability goals."

"It's tough to say we're the greatest renewable company in the world [if] we have a bunch of tractors running up and down our fields belching out CO2," he continued.

Another advantage, Charpie said, is that at the end of the solar array's lifespan, the land beneath it will be restored and refreshed.

"We have all these sheep now who will spend 30-plus years breathing, living, using their hooves to churn up ground, even dying; it's the circle of life," he said. "When these farms get turned back to the families, that soil condition will be wonderful."

'He saw an opportunity here'

Gerlach's family had about 50 ewes when the idea for grazing around the solar panels struck. He "hounded" Acciona, in Charpie's words, to bring an agrivoltaic deal to fruition.

"He saw an opportunity here, and he has been his own best advocate, banging down the door, checking how close are we, when will we get our sheep here," Charpie said.

Gerlach ultimately bought about 500 sheep of two types: Dorper and Katahdin, small breeds that can fit easily under solar panels.

"The panels create lots of shade - during the heat of the day, they'll all be underneath the panels for shade," Gerlach said. "In early mornings, late evenings they're out grazing aggressively. They don't bother the panels one bit."

Gerlach said his family "used to raise livestock like everybody did back in the day," and his farm has won awards for its cattle, but raising livestock has become less profitable in recent years. Agrivoltaics offer an opportunity to delve back into raising sheep, something Gerlach loves. A commercial sheep operation would only be possible with the payments for vegetation management, he said.

"Raising sheep in the United States is challenging because the market for sheep is not very high," he said. There's not much of a domestic wool market, and "the meat side of sheep and lamb never really caught on in the U.S. - we're a beef, pork, poultry-consuming country."

Gerlach sells the bulk of his lambs around the Easter season, and largely for kosher and halal consumption. Since that market is so limited, the ewes largely earn their keep being paid to graze.

"We love providing stewardship to the animals. That's what U.S. agriculture was built on hundreds of years ago," Gerlach said. "It marries really well with our crop production" on nearby land. "In agriculture you need diversification. By bringing sheep and livestock production in, we can afford to hire more full-time employees."

Sheep are the livestock best suited to agrivoltaics, stakeholders agree.

"You can't use cattle because they're too large, they would rub on the panels and break them," Gerlach said. "You can't use goats because goats would climb on the panels, and they're natural chewers, they would chew on the wires."

The High Point solar array is divided up into separate plots with fences, "like perfect little pens for the sheep," added Charpie.

In a bigger uninterrupted plot, a farmer would likely need to move water sources for sheep strategically around the area to make sure the animals cover the entire plot. Gerlach's flock only grazes about a fifth of the Acciona solar array. He's hoping to expand, though feeding and sheltering sheep during the winter when they can't graze is costly.

"I've got three young kids. Hopefully we raise them in agriculture. It's such a good practice for our young people to learn responsibility and stewardship," Gerlach said.

"[The animals] come first, they get fed and watered and taken care of before us. Sometimes agriculture gets portrayed in a poor light, especially larger production agriculture. I try to really push that that's not everybody. Talk to a local farmer, a local person - you generally see that we're stewards of the land, we want healthy ground and livestock. That can marry in fine with clean energy."

Conservation groups are celebrating the end of a Massachusetts-based biotech company's pursuit of bringing genetically altered Atlantic salmon to market.

AquaBounty was the first company to get regulatory approval from the Food and Drug Administration to sell a genetically modified animal for human consumption in 2015, but it faced continuous legal challenges and consumer pushback.

Dana Perls, food and technology senior program manager with Friends of the Earth, said people just don't want to eat it.

"Grocery stores are refusing to sell it," said Perls. "Big restaurants are refusing to sell it. So, it's a market response."

Perls said the altered salmon put wild salmon - along with the fishing and Indigenous communities that rely on it - at risk.

In a statement, AquaBounty says it failed to raise enough capital to maintain its operations.

AquaBounty's AquaAdvantage brand salmon contained added genes from both Chinook salmon and the eel-like ocean pout to make it grow faster.

But polls show most Americans believe genetically engineering animals for protein production isn't an appropriate use of biotechnology.

Perls said consumers are increasingly rejecting industrial food production, and demanding their food be clearly and accurately labeled.

"People want to be able to choose what it is they're eating and what they're feeding their families," said Perls, "and we need to ensure that the food we raise is truly healthy, truly sustainable, and fully regulated for safety."

Perls said the demise of AquaBounty salmon will set a precedent for other companies investing in genetically altered animals.

At least 35 fish species are currently being modified around the world, including trout, catfish, and striped bass. The FDA has also approved genetically altered pigs and cows for food and medical use.

Farmers in North Dakota and the rest of the country are monitoring an evolving legal case against a giant equipment manufacturer and they said repair restrictions are not the only service headaches farmers encounter.

The Federal Trade Commission last week sued John Deere, accusing the company of an unfairly dominant market share. It said farmers have to rely on Deere's network of authorized dealers for necessary repairs, driving up costs and creating scheduling delays.

Mark Watne, president of the North Dakota Farmers Union, said he hopes the case brings out the facts in securing a resolution. He added the need for flexibility covers other ground, too.

"Items such as technology fees, and items such as, 'Well, you can only use this chemical with this seed, and it's got to be this brand,'" Watne outline. "Those things start to play out that we think are concerning."

He pointed out another area is transportation, where farmers might encounter vastly different price structures in getting their commodities shipped out, depending on the railway competition in various parts of the country. John Deere called the lawsuit "meritless," and said it plans to offer self-repair capabilities as farmers work with emerging technologies on tractors.

Watne acknowledged depending on the administration in the White House, they will see either aggressive or more lax approaches in confronting repair issues. He sees a long-standing pattern of laws being underutilized.

"There's really rules in place that have been there for 50 years or more that, through a number of administrations, haven't necessarily been enforced," Watne emphasized.

He admitted some of the progress seen in the Biden administration faces an uncertain future in the second term of President-elect Donald Trump, as some Trump appointees might prioritize certain fairness issues but could pass on other concerns voiced by smaller, independent farmers. Trump's selected appointee for FTC Chairman has been a vocal critic of the John Deere lawsuit.

The future looks promising for green energy and manufacturing in Appalachia, and states like West Virginia are slated to receive around $1 billion in federal investment since the passage of the Inflation Reduction Act, according to experts at ReImagine Appalachia's virtual strategy summit held earlier this week.

A Reimagine Appalachia report has found West Virginia and other Appalachian states are home to a higher-than-average share of manufacturing employment.

Jacob Hannah, CEO of Huntington-based nonprofit Coalfield Development, explained large manufacturing facilities are moving into the state, bringing new local jobs along with them.

"They're focused on localizing energy production at their sites," Hannah pointed out. "Because they consume a lot of energy and they're focused on workforce development because they need to hire a lot of folks and train a lot of folks."

Last year the Biden administration announced $475 million for projects in West Virginia and other states to boost clean energy development on current and former mine land. The funds will be used in Nicholas County to repurpose two former coal mines with utility-scale solar infrastructure, to power around 39,000 homes and create hundreds of construction jobs.

Solar development on degraded land and brownfields is expected to increase, along with use of residential solar. West Virginia's Office of Energy received $106 million last year from the Environmental Protection Agency's Solar for All
program to install solar panels on homes and reduce utility costs for low-income residents.

Mustafa Santiago Ali, executive vice president of the National Wildlife Federation, said continued federal investment is needed to help Appalachian residents build in healthy and thriving communities.

"We need to ensure communities without clean air and water, especially those suffering disproportionate environmental burdens from years of disinvestment and legacy pollution, get the funding and support that they need," Santiago Ali urged.

Green industries manufacturing alternatives to plastic including biodegradable and mycelium-based products are also on the horizon as potential regional economic drivers.
