A big concern with large-scale solar farms is the impact on land use. Solar developers often site projects on agricultural land that is taken out of production. Also, the vegetation around solar panels needs to be maintained to prevent shading. In some cases, herbicides are used, contaminating waterways, and mowing generates pollution. If the developer applies gravel or plants turfgrass, the land has little wildlife value.
As the local food movement gains steam, isn’t it counterproductive to turn productive cropland into an energy plant? How can the solar energy industry embrace biodiversity while producing clean energy? Is dual use of a solar site possible?
Solar farms can be managed to increase pollinator habitat, improve soil quality, and even for livestock grazing. Innovative land management approaches enable solar projects to serve multiple purposes, benefitting the local economy. Keeping honeybees, grazing sheep, and even cultivating mushrooms can all complement a solar energy project.
Native Wildflowers Boost Pollinator Habitat
Researchers with the Argonne National Laboratory are examining the economic benefits of establishing native vegetation, including wildflowers and prairie grasses, on nearby cropland. Native vegetation attracts crucial critters like bees, flies, bats, birds, wasps, moths, and butterflies, which can be beneficial to crop yields.
