A new report showed biomass energy and wood-pellet production may be worse for human health and air pollution in comparison to fossil fuels across North Carolina.

The study found facilities burning biomass release almost three times the number of pollutants compared with places burning fossil fuels.

Sarav Arunachalam, professor and deputy director of the Institute for the Environment at the University of North Carolina, said while the option has been viewed as renewable, there are still health risks.

"There are a lot of hazardous air pollutants also quantified from the study, and they may have other health space endpoints beyond just premature mortality, and these could be cancerous, noncancerous, and so on," Arunachalam explained. "It's a very broad mix of adverse health impacts, but the top one would be fine particulates matter."

Arunachalam pointed out while the demand for biomass within the U.S. remains stagnant, there is a growing market for exporting it to Europe which could further affect communities in the future. In 2021, biomass accounted for nearly 2% of North Carolina's electricity.

Edie Juno, forestry specialist for the National Wildlife Federation and co-author of the study, said wood-pellet facilities could also be emitting more than they claim on their permits, based on data they found in permit applications and national emissions inventories. She suggested it could signal the need for more enforcement.

"We need the state regulatory agencies to be aware of these patterns and really discerning as they're reviewing the permit application," Juno contended. "We probably need support from EPA in terms of enforcement of different air quality permits as well. "

According to the study, biomass contributes 3% to 17% of the emissions from the entire U.S. energy sector. Both researchers noted despite the number being seemingly low, more information is needed to uncover the true effects the facilities have before further investment into the technology.

A major player in the Northwest's energy landscape is considering changes in the future, as extreme climate events make power delivery in Oregon more unpredictable.

Like utilities in the region, the Bonneville Power Administration - a nonprofit federal administration - is considering joining a larger energy market to ensure reliable access for customers.

BPA is favoring a market known as Markets+, which it says will be less expensive in the long run but could cost between $79 million and $129 million more for ratepayers in 2026.

However, organizations like Save Our Wild Salmon favor the Day-Ahead Energy Market, or EDAM.

Tanya Riordan, policy and advocacy director with the organization, said BPA needs to consider tribal rights in the region, especially when it comes to salmon.

"We can have a more open governance model," said Riordan, "that gives state officials and consumers an equal role, which would keep salmon recovery priorities at the forefront, which is what the EDAM market would offer."

Riordan said the transition to a larger energy market would reduce pressure on the federal hydropower system, also reducing pressure on the region's rivers and salmon.

A formal document outlining BPA's decision is expected in May.

Ben Otto, an energy consultant with the Northwest Energy Coalition, said he also favors EDAM.

He said the BPA has a unique role in the Northwest, with obligations to its customers, but also to the rest of the region by selling hydropower to keep bills low and running a transmission grid in the Northwest.

"Also by mitigating the impacts to salmon and wildlife and tribal interests," said Otto, "this is really important - and we really think that those obligations need to play a more significant role in Bonneville's decision, and we look forward to that being reflected in their record."

Otto said EDAM would reduce costs and be just as reliable as Markets+, and would make the integration of clean energy easier.

He noted that BPA wouldn't fully join the market, regardless of its choice, until 2028 - and so he's urging the administration to take its time making a decision.

"We believe a market that gives a strong role for public interest and state policy is a better fit for Bonneville's obligations than Markets+," said Otto, "which is really more of like a business league and more commercially focused."

The U.S. military and a nonprofit environmental group are seeing success in a partnership that strengthens military readiness and conserves Indiana's natural resources.

Some military installations have compatible land uses around them, such as farms and forests, wetlands and grasslands. Sentinel Landscape, a federal initiative managed in part by the Department of Defense, works with nonprofits to manage those lands.

Emy Brawley, Midwest Region vice president at the Conservation Fund, said southern Indiana received a Sentinel Landscape designation in 2022, allowing her organization to work with bases across the region.

"That designation is supporting four Department of Defense installations, including the Lake Glendora test facility," she said. "All four of those installations provide a wide number of testing and training opportunities for multiple branches of our military."

Brawley said it's important to protect lands around military sites from encroachments that impact the military's ability to maintain mission readiness. She added that commercial developments near military bases can cause noise or light pollution that restricts training and testing drills.

Brawley's organization works in the new Busseron Creek Fish and Wildlife Area, the largest conservation project in Indiana in 20 years. The site serves as a buffer of undeveloped land near the Lake Glendora Test Facility, a military base.

Brawley said the area's natural resources are critical for certain species of wildlife in Indiana.

"This new Fish and Wildlife Area protects a five-mile segment of Busseron Creek, along with forests and wetlands and grasslands and streams and lakes," she said. "In fact, a nearby Fish and Wildlife Area documented over 250 different bird species using it."

Brawley said protecting the land in the new fish and wildlife area will make it more functional as a training and testing site. It also allows for public access and recreational activities such as fishing, hunting and camping.
