There Is One Clear Winner in the Corn vs. Solar Battle (cleantechnica.com)
“Solar energy is often framed as a threat to croplands. However, vast croplands in the Midwestern United States already support corn ethanol biofuel, a form of energy with a greater land-use footprint per unit energy (~30×) and potential environmental impact (e.g., excessive fertilizer application) than solar energy. We envisioned sustainable agro-ecosystems that can result from converting a small proportion of corn ethanol croplands into ecologically informed solar facilities (i.e., ecovoltaics).
