Agrivoltaics: 3x Land Use Efficiency vs Ethanol – Food, Jobs & EV Power

Chicagoans have always been practical. From the rebuilding after the Great Fire to the city’s embrace of innovative architecture, there’s a current of resourceful problem-solving running through the city’s veins. That spirit is about to be tested – and potentially rewarded – by a shift in how we think about land use, energy, and food production. The idea? Trading some of the land currently dedicated to growing corn for ethanol, and repurposing it for solar energy facilities, isn’t just environmentally sound, it’s a surprisingly efficient way to boost food production and strengthen our local economy.

The Agrivoltaics Revolution: More Than Just Solar Panels

For years, the debate around renewable energy has often framed it as competing with agriculture for precious land. But what if we could have both? That’s the promise of agrivoltaics – the co-location of solar panels and agricultural production. Recent research, detailed in a comprehensive review published in Renewable and Sustainable Energy Reviews this month, suggests that agrivoltaics isn’t just a compromise, it’s a synergistic solution. The study highlights that strategically implemented agrivoltaics could add over 1800 million tonnes to global crop yields annually, potentially feeding more than 2.1 billion people each year. That’s a staggering figure, and one that deserves serious consideration here in the Midwest.

The benefits extend beyond simply increasing food production. Agrivoltaics can significantly reduce water usage, improve land efficiency, and even enhance crop quality. The solar panels provide shade, reducing water evaporation and protecting plants from extreme temperatures. Here’s particularly relevant in Illinois, where summers are becoming increasingly hot and dry. The panels can alter the microclimate, creating a more favorable environment for certain crops. The research also points to the potential for over $1 trillion in added global agricultural income, a substantial economic boost.

From Ethanol to Electrons: A Strategic Shift for Illinois

The Cornell University report specifically points to the potential of converting land used for corn-ethanol production to solar facilities. This is a particularly pertinent point for Illinois, a major corn producer and a significant contributor to the nation’s ethanol supply. While ethanol has been touted as a renewable fuel source, its environmental benefits are increasingly debated, and its production requires vast amounts of land and water. A strategic shift towards agrivoltaics could allow Illinois to maintain its energy production capacity while simultaneously increasing food security and reducing its environmental footprint.

This isn’t about eliminating corn production entirely. It’s about optimizing land use. The study suggests that even a compact fraction of land currently dedicated to corn-ethanol could produce a significant difference. The PNAS study also highlights the importance of co-locating solar PV with perennial vegetation to filter excess nutrients, a crucial consideration for maintaining water quality in the Great Lakes region.

The Role of Chicago’s Institutions

Several Chicago-area institutions are already positioned to play a key role in this transition. The University of Illinois at Urbana-Champaign’s Prairie Research Institute is conducting cutting-edge research on sustainable agriculture and renewable energy, and could be instrumental in developing agrivoltaic systems tailored to Illinois’ climate and crops. The Illinois Department of Agriculture will be crucial in implementing policies that incentivize farmers to adopt agrivoltaics. And organizations like the Chicago Council on Global Affairs can help raise awareness about the benefits of this approach and advocate for its widespread adoption. Even the City of Chicago’s Sustainability Office could explore opportunities for implementing agrivoltaics on city-owned land.

the Illinois Power Agency could play a vital role in creating a regulatory framework that supports agrivoltaic projects, ensuring fair compensation for farmers and promoting the integration of renewable energy into the grid. The success of agrivoltaics in Illinois will depend on collaboration between researchers, policymakers, and the agricultural community.

Navigating the Transition: Local Expertise You’ll Need

Given my background in sustainable land management, if this trend impacts you in the Chicago area – whether you’re a landowner, a farmer, or a community member – here are three types of local professionals you’ll need to navigate this evolving landscape:

Agrivoltaic System Designers & Installers:

Look for firms with proven experience in designing and installing agrivoltaic systems, specifically those familiar with Midwestern climates and agricultural practices. They should be able to assess your land, recommend appropriate panel configurations, and ensure the system integrates seamlessly with your existing farming operations. Certification from the North American Board of Certified Energy Practitioners (NABCEP) is a strong indicator of competence.

Agricultural Land Use Attorneys:

Navigating the legal and regulatory aspects of agrivoltaics can be complex. You’ll need an attorney specializing in agricultural land use law who understands zoning regulations, easement agreements, and renewable energy incentives. They should be able to help you secure the necessary permits and ensure your project complies with all applicable laws.

Sustainable Finance Consultants:

Agrivoltaic projects require significant upfront investment. A sustainable finance consultant can help you identify funding opportunities, including grants, tax credits, and low-interest loans. They should have a strong understanding of renewable energy financing and be able to develop a comprehensive financial plan for your project. Experience with USDA programs is a plus.
