ORNL: Bioenergy – For the birds

An analysis by Oak Ridge National Laboratory showed that using less-profitable farmland to grow bioenergy crops such as switchgrass could fuel not only clean energy, but also gains in biodiversity.

Researchers examined segments of land in the Midwest responsible for a loss of approximately $110 million per year from 2013 to 2016. If about 3% of those areas were converted to switchgrass, they could generate about 7.6 million dry tons per year of plant material for use in biofuels and bioproducts.

Growing native grasses could also help birds, increasing species diversity by up to 8% according to models developed by ORNL’s Jasmine Kreig.

“Finding ways to grow crops for economic benefit that also help restore habitat for grassland bird species is a win-win,” ORNL’s Henriette Jager said. “This is an opportunity to achieve both renewable energy and conservation goals.”
