Minnesota has plenty of prime farmland, with some of it being converted in the transition to clean energy sources such as solar. The movement has sparked conversations about future land use in ag-heavy areas.

The Clean Grid Alliance said Minnesota has 17 million acres of farmland considered "prime." Even if all current development plans are fully realized, solar would take up less than 0.5% of the total. However, in some farming communities, residents sometimes express reluctance about adding a new layer to a town's identity.

Trish Harren, Mower County administrator, said it can happen after visible signs of a solar project but she pointed out the economic benefits are substantial.

"As solar builds out, it will be an economic-development tool that will help us keep our tax base stable," Harren explained.

Harrin noted they have already seen the same effect with wind development and the pending Louise Solar Project is expected to provide more than $2 million in new tax revenue to help pay down local tax levies. Officials said the revenue is on top of direct payments to landowners hosting the projects.

Harrin stressed as they map out future land use, they have to strike a delicate balance because agriculture is still their primary economic driver.

Researchers at Virginia Tech are looking at the possible connection between larger solar farms and soil erosion along farm property.

Marlin Fay, president of the Mower County Farm Bureau, suggested whatever side effects might come up, the projects are not going to eliminate the nation's ability to grow food.

"If you have solar panels on the land for 30 years, they can come out of there and that land can go back to farming," Fay explained. "If you start having residential development and big business or something, come into farmland and start putting stuff on there, that's never going to go back to farmland again."

The local leaders also pointed to the emergence of agrivoltaics, which is farming and renewables working hand in hand. Examples include growing rows of crops in between or under canopies of solar panels or planting flowers around the installations so pollinators can float around them.

The Public Service Commission of West Virginia is facing legal challenges for its 2021 directive that Appalachian Power increase the usage of three of its coal plants.

Critics say the utility is paying more to keep coal plants open, and passing the cost onto residents and businesses - now burdened with higher energy bills.

The lawsuit argues that the mandate oversteps federal rules and undermines safeguards put into place to protect the public from unfair rate increases - according to Jim Kotcon, chair of the West Virginia Sierra Club.

"Sixty nine percent is a much higher rate than these coal-fired power plants have operated at in the past," said Kotcon, "and by directing the plants to operate at that level, it forces the utility to sell electricity into the grid at a price below their cost of operating."

According to the Sierra Club, rates have jumped by an average of 20% since the directive went into effect in 2021, resulting in significantly higher electricity bills.

The Commission argues the directive is aimed at meeting an increased demand for energy.

Research shows West Virginians' average monthly residential energy bills have more than doubled over the past decade, from about $67 to $142 per month.

Bruce Perrone is a retiree in Kanawha County who said older and low-income residents, and those living on fixed incomes, will bear the burden of higher energy bills.

He added that state regulators are tasked with ensuring that power companies charge reasonable rates.

"My problem with this whole scheme is telling them to run their coal-fired businesses at levels where they're going to lose money is just a means to support the coal industry," said Perrone. "It is not helping consumers."

Last month, Appalachian Power filed another rate increase request with the Commission, seeking to raise its annual revenue by $265 million.

Researchers mapped American croplands that have fallen out of production in hopes of inspiring new uses for them, such as renewable energy.

Roughly 30 million acres of croplands in the United States have been abandoned since the 1980s, including 1.5 million in South Dakota, according to a recent paper.

Tyler Lark, research scientist at the University of Wisconsin-Madison and one of the report's co-authors, said some lands have been restored to natural ecosystems. Others, those perhaps currently populated by invasive species, could be the answer to big questions the country is facing about where to house increasing renewable-energy development.

"We ideally want to avoid our best and most productive ag lands but we also don't want to encroach on pristine or native ecosystems," Lark explained. "Formerly cropped lands might hit that sweet spot in the middle."

Lark pointed out those acres could be used for biofuel, wind or solar production. Legislators have written bills to promote renewable-energy development without threatening the country's richest soils. One example is the Protecting Future Farmland Act, introduced last September by Sen. Tammy Baldwin, D-Wis., and Sen. Chuck Grassley, R-Iowa, which would facilitate what advocates call a "smarter solar buildout."

The American Farmland Trust estimated about 83% of new solar projects are built on farmlands and a majority of those on what's considered "prime" agricultural lands. Lark hopes research can help avoid conflicts over land use.

"At the local land-use planning level, where you have potential competition between different land uses, this data could potentially help facilitate that conversation and guide some of those investments," Lark contended.

Some renewable energy projects can coexist with agriculture. According to research from the U.S. Department of Agriculture, farmlands where wind turbines were installed between 2009 and 2020 typically stayed in farm production, while about 15% of farmlands where solar power was added shifted out of agriculture.

At Long’s Pic Pac in Pineville, Kentucky, Mike Long is finding an innovative way to cut down on electricity costs. Solar panels cover the roof of the small-town grocery. A 60KWh battery allows Long’s Pic Pac to store solar energy, vastly reducing the peak demand charges that make up more than half the store’s monthly power bill.

Long is the general manager of the grocery business started in 1964, when his father Arthur “Ray” Long got a $3,500 loan co-signed by an appliance store owner who knew Ray from watching him play football. Mike was only a few years old when his father’s grocery store opened. He grew up with the business.

Today, he’s determined to keep Long’s Pic Pac the grocery store of choice for Pineville, a town of about 1,630 people in Southeastern Kentucky. “There’s only one cell tower,” Long said of Pineville. “You can run around the whole town in about three miles.”

Long thinks Pic Pac might be the first grocery store in Kentucky to install solar with battery capacity to lower the high demand charges of refrigeration, deli ovens and fryers. A Rural Energy for America Program (REAP) grant from the U.S. Department of Agriculture funded 40% of the project.

The business is also eligible for a 30% federal tax credit on the 143kW solar array, with a longer depreciation because Pineville is a low-income community. The median household income in Pineville was $27,159 in 2022, according to the U.S. Census Bureau.

In the Appalachian region of Kentucky, more than 20 percent of the population regularly experiences hunger, and keeping the lights on in rural grocery stores helps reduce food insecurity. Long projects an estimated cost savings from the solar array and battery storage of at least $15,000 per year. That savings could be used for staffing in the perishable departments and offset added field costs in delivery.

Grocery stores run on a razor-thin 2.2% profit margin, making them among the least profitable industries in the U.S .“Tight margins are one of the reasons why many rural places have seen full service stores struggle to keep their doors open,” said Long.

Long learned about the REAP grant through the Mountain Association, a nonprofit that works to help Eastern Kentucky transition to a more diverse, equitable, sustainable and resilient economy. Solar Energy Solutions installed the array.

Long expects to be able to pay back the cost of the project in four years. At the grocery store, power can cost as much as $78,000 annually. On a monthly bill, the power charges might be $2,600, while the store might pay $3,900 for the “demand charge,” based on the highest amount of power used.

Around 2017, Long’s Pic Pac upgraded the refrigerated cases in the produce meat and deli departments with motion-detector lighting and doors to conserve energy and freshness, using a then-20% REAP grant. The store will be replacing freezers and an older refrigeration motor room later this year with a REAP grant. Long said that competition for energy savings grants is increasing as more people hear success stories.

He aims to be a small-town store ahead of the curve. “None of the chains have solar,” he said, adding that he doesn’t know of any chains using solar like Long’s Pic Pac. “We’ve got more green, newer stuff than any of them.”

As with the grocery store, “people take pride in the town,” he said. Long’s Pic Pac also draws on customers from surrounding communities and unincorporated areas, despite the presence of larger stores within a 15-minute drive. Several thousand customers a week walk through the doors at Long’s Pic Pac.

“Our sales floor is only 11,500 square feet,” Long said. “We’re small here, but everybody feels like it’s a small thing that we make the most out of,” he said.
