COLUMBUS, Ohio - "Going green" is a matter of faith for some houses of worship in Ohio. They are implementing measures that save money and help the environment. At First Presbyterian Church of Athens, Pastor Rob Martin says addressing greenhouses gases that lead to climate change seems like an overwhelming challenge, from a global perspective. But he says if each person takes simple steps to reduce energy use, it will add up and make a difference.

"We looked at it from a theological perspective of caring for creation, that we're called to find out ways we can have more sustainable kinds of energy use in our daily lives," he says

First Presbyterian Church of Athens was recognized for its energy-efficiency efforts in the Environmental Protection Agency's 2013 ENERGY STAR National Building Competition. Martin says they reduced energy use 20 percent for the past 12 months and in the process, prevented an estimated 9.2 metric tons of greenhouse gas emissions.

With the assistance of Ohio Interfaith Power and Light, as well as Columbia Gas and AEP Ohio, Martin says his church used a variety of strategies to reduce energy use.

"We were fortunate enough to partner with the local utilities companies to help pay for the audit and then also help pay for the upgrades," he says "We discovered we could save money if we purchased a new boiler system, changed our lights over to LED lights, and did some insulating around some windows."

Martin says the energy-efficiency steps they are taking at the church are inspiring members of the congregation to look at ways they can save energy in their own lives.

"People have asked us questions about, 'Is that something I can do in my own home; is this something I could even do in my own business?' So, I think we're looking to the future in terms of just getting the word out," says Martin.

The Pastor adds, they will continue to look for ways to reduce energy consumption and hope to share their knowledge with other congregations. Energy use in commercial buildings is estimated to account for almost 20 percent of total U.S. greenhouse gas emissions.

Overseas markets could be harming forests in the U.S. Demand for wood pellets for biomass energy has increased dramatically around the world, especially in Europe where burning wood is treated as renewable energy and heavily subsidized.

The UK-based company Drax Group plans to build a 450,000 ton per year wood pellet plant in Longview.

Peter Riggs, director of the Washington state-based nonprofit Pivot Point, said the region has a productive wood sector.

"This new wood pellet plant proposed for Longview is very different," Riggs pointed out. "First of all, it's not for the domestic market, it's not making pellets for home stoves. It represents a substantial and entirely new source of wood fiber demand for export."

Riggs said much of the biomass would be bound for Asia. His organization signed a letter, along with more than 100 others in the U.S. and Canada, calling for the European Union to stop incentivizing wood burning as renewable energy.

Laura Haight, U.S. policy director for the Partnership for Policy Integrity, said despite its label as renewable energy, burning wood from forests one of the worst activities for the environment. It releases emissions when burned and removes trees that store carbon. Haight's organization also signed the letter to the European Union, urging it to no longer classify forest biomass as renewable.

"It's the money that's driving this system," Haight asserted. "If they change that policy, then this will no longer be subsidized, and we can see a better future for our forests and for our climate."

Riggs noted solar and wind energy were subsidized, and the costs have gone down dramatically. However, the same is not true for forest biomass. He emphasized plant operators have struggled to reduce the costs involved in sourcing, transporting and burning biomass fuels.

"If they're going to subsidize it, you kind of got to subsidize it forever," Riggs contended. "But with wind and solar, those are already cost-competitive."

The U.S. Department of Agriculture has awarded Iowa State University a $1.8 million grant to raise high-dollar crops in the shadow of huge solar array panels that are becoming more common across the state.

Ag researchers and energy experts are studying ways for people to benefit from investments in renewable energy beyond just clean electricity.

It's called agrivoltaics, and it couples solar farms with agricultural practices in, around and underneath huge solar panels, where the resulting shade won't allow traditional agricultural crops to grow well.

Matt O'Neill - professor in plant biology, entomology and microbiology at Iowa State - said researchers are trying what are known as horticultural crops in the shadow of the solar arrays, crops he said could grow better and also tend to be more valuable.

"It's a mix of things," said O'Neill. "It can be things like broccoli, tomatoes, squashes - but also perennial crops like strawberries and blackberries and raspberries. "

O'Neill said Iowa's corn and soybeans, known as commodity crops, need a lot of land to be grown profitably - which is why he says 70% of Iowa's landscape is planted with them.

He said the growing number of solar farms will create more available land for horticultural crops, potentially creating another avenue for people who want to get into farming on a smaller scale than commodity crops such as corn and soybeans require.

O'Neill said there is some evidence that growing horticultural crops beneath the panels creates a cooler micro-climate, allowing the solar arrays to operate more efficiently when they are producing electricity.

Anne Kimber directs the Electric Power Research Center at Iowa State. She said given all of the benefits, she wants people to understand that using farmland in multiple ways - as agrivoltaics does - will be economically and environmentally beneficial for everyone.

"But that means that we're using land in a different way for those kinds of home-grown power systems," said Kimber. "And if we can demonstrate multiple values from these projects, then it does have greater value for the state of Iowa. It has greater value to the people who see these developments happening around them."

Construction on the 1.35-megawatt solar-farm agrivoltaics test site will begin next month on 10 acres south of Ames. Research is scheduled to begin next spring.

Tucson community leaders gathered at an event to highlight opportunities to grow Arizona's clean-energy economy say it's been made more accessible through incentives in President Joe Biden's Inflation Reduction Act and the Infrastructure Investment and Jobs Act.

Tucson City Council member Kevin Dahl predicted that clean-energy incentives will not only help lower-income households in the state consider solar but will also address a previous gap in benefits for nonprofit organizations. The IRA bill allocates $20 billion for nonprofits to implement projects that cut pollution and energy costs.

"Even as the clean-energy industry has exploded in our state, a lot of Arizonans have been left out," he said. "New solar incentives, however - including a 30% tax credit off the cost of installation and another 30% for standalone battery installation - will be transformative."

Leaders have estimated an additional 150,000 Arizona households will install rooftop solar panels because of the investments present in the Inflation Reduction Act.

More solar power may also be coming to rural Arizonans, with increased funding for the Rural Energy for America Program. It provides grants and loans to farms and small businesses that invest in clean-energy technology.

Robert Neifert, director of business development for Solar Gain, Inc. and co-chair of the Arizona Solar Energy Industries Association, said he's excited about what this could mean for Arizona. He said they're already seeing an uptick in business.

"We were looking at the tax credit going down to 22 [percent], and then down to 10 [percent], and wondering what would happen to solar, in Arizona and the country," he said. "And now, it's turned the other direction and we're more excited than ever. And having 10 years of certainty is absolutely amazing."

Neifert said what is important about the clean-energy transition is that it be accomplished affordably and executed fairly. As some members of Congress try to roll back investments in clean energy, all speakers at the event shared an urgent need to continue with what they called "bold climate action."
