Solar vs Corn for Ethanol: Which land use produces the most energy? State of Change
-
- Society & Culture
We’re hearing it more and more: Solar farms in Wisconsin are taking away prime farmland used for food. But it turns out, a million acres of farmland in Wisconsin are already being used energy production by growing corn for ethanol. A quarter of all the corn grown in our state is processed into ethanol. Nationwide, it’s 45%.
But which land use produces the most energy per acre, corn or solar? And how much land do we really need for solar in Wisconsin to end our reliance on coal and gas? Hear from Clean Wisconsin Science Program Director Paul Mathewson, Ph.D., about his latest analysis that’s been getting a lot of attention.
Host: Amy Barrilleaux
Guest: Dr. Paul Mathewson, Science Program Director, Clean Wisconsin
