The age-old debate of food versus fuel is a topic that never fails to spark fiery discussion. But what if we were to look at it from a different angle – land use?

In recent times, the solar industry has received criticism for gobbling up large swathes of land, particularly fertile farmland, for the purpose of energy generation through photovoltaics. This begs the question: What if we were to harness that land for solar energy instead?

Tennessee, in particular, has found itself at the forefront of this debate due to its significant use of land for ethanol production. The University of Tennessee Institute of Agriculture revealed that over 900,000 acres of corn were sown in the state last year, with a substantial chunk, estimated at 30%, going towards ethanol production. This means that a staggering 270,000 acres of land in Tennessee are being dedicated solely to ethanol production.

On the other hand, a recent report from the same institute delved into the potential for land use of utility-scale photovoltaics on farmland in Tennessee. The report revealed that if the Tennessee Valley Authority (TVA) goes ahead with its plans to have 10 gigawatts of solar energy by 2035, it could potentially occupy anywhere from 57,514 to 103,443 acres of land, which accounts for a mere 0.22% to 0.39% of the state’s total land mass, or 0.53% to 0.96% of Tennessee’s farmland.

With these figures in mind, it’s evident that there is significant potential for a shift in land use from ethanol production to solar energy. According to the UT study, the estimated land required for 10 GW of solar in Tennessee could easily accommodate the land currently used for ethanol production. And let’s not forget, solar energy is more efficient and offers farmers a more predictable income through solar leases.

As the world gradually steers away from gasoline-powered vehicles, the demand for ethanol is likely to dwindle, making now the perfect time to consider repurposing the land for more sustainable energy sources. The potential financial and environmental benefits of switching from ethanol to solar are undeniable.

The idea of land being utilized for solar energy instead of ethanol has already piqued the interest of experts. A study from UC Davis comparing energy metrics and the financial returns of farmers from planting solar panels or corn serves as evidence of the growing intrigue surrounding this topic.

The issue of ethanol subsidies, often seen as more politically motivated than economically viable, also comes into play in the decision-making process for farmers. How these subsidies influence the choice between land use for ethanol or solar is a crucial factor that cannot be overlooked.

The transition from ethanol to solar energy presents an exciting opportunity for change and growth in the farming and energy sectors. The potential for positive environmental and financial impacts is immense, and it’s a shift that could pave the way for a more sustainable and energy-efficient future.
