Bumblebees buzz from flower to flower, stopping for a moment under a clear blue Minnesota sky. Birds chirp, and tall grasses blow in the breeze. This isn’t a scene from a pristine nature preserve or national park. It is nestled between photovoltaic (PV) solar arrays on rehabilitated farmland.
Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and National Renewable Energy Laboratory wanted to understand the ecological value of PV solar energy sites planted with native grasses and wildflowers. They examined how vegetation would establish and how insect communities would respond to the newly established habitat. The five-year field study looked at two solar sites in southern Minnesota operated by Enel Green Power North America. Both sites were built on retired agricultural land.
Smart land use choices provide multiple benefits
Global insect biodiversity has been in decline due to habitat loss, pesticides and climate change. Restoration of insect habitat paired with smart land use changes toward renewable energy developments could help reverse the course.
