New Michigan State University (MSU) research suggests farmers don't need to choose between growing crops and installing solar panels; in fact, both can coexist. Leveraging this innovative land use approach can result in greater financial security and save water.
As increasingly extreme weather threatens global food, energy, and water resources, new energy sources are vital for reducing carbon emissions. However, the solar boom has often raised concerns about reduced food production.
The MSU research team analyzed remote sensing data and aerial imagery to study how ag fields have been used in California for the last 25 years and then used existing databases to estimate farmer revenues, costs, and potential energy sales. The results showed that farmers using just a few acres for solar gained significant financial stability. They spent less on fertilizer, water, and farming supplies and gained income from selling excess energy which offset any decrease in crop yields.
There are plans to extend this type of study across the continental US and to explore broader environmental impacts. It is hoped that this research will inform future debates on optimal land use, while also ensuring food production isn't compromised.
