Recent Solar Energy Industries Association research argues that concerns over converting farmland to solar are overstated because utility-scale solar currently occupies only 0.07% of U.S. farmland. The statistic is accurate. The conclusion deserves closer examination.
The issue applies not only to utility-scale projects, but to solar development more broadly wherever energy production competes with agriculture for productive land.
Not all farmland is the same
The relevant policy question is not how much farmland solar occupies today, but how society should steward its most productive land. The 0.07% statistic uses all U.S. farmland as its denominator—including cropland, pasture, rangeland, woodland, and other categories. One acre of highly productive irrigated cropland cannot simply be replaced by one acre of marginal grazing land.
Solar developers seek flat, contiguous parcels with excellent road access, nearby electrical infrastructure, and favorable permitting conditions—the same characteristics that can make highly productive farmland especially attractive.
A national percentage also says little about communities where one project can transform the character of a rural township. Farmers and rural communities have a legitimate voice in decisions affecting their livelihoods, landscapes, and long-term economic futures.
A Strategic Agricultural Reserve
The United States has roughly 360 million acres of cropland, about 200 million of them classified as prime cropland. There are also 13.5 million acres of idle cropland not enrolled in federal conservation programs and available for agricultural use.
Even if every idle acre were suitable for high-quality production, it would equal only about 6.8% of the nation’s prime cropland base. The real reserve of readily available prime cropland is likely smaller. This land should not be seen as up for grabs, but as part of a Strategic Agricultural Reserve: high-quality agricultural capacity and flexibility held for an uncertain future.
We maintain reserves of petroleum, critical minerals, military equipment, and medical supplies because future disruptions cannot be predicted. Prolonged drought, aquifer depletion, crop disease, geopolitical instability, population growth, and changing diets could dramatically alter where food can be produced. Agricultural flexibility deserves the same foresight.
A better objective
The urgency of deploying renewable energy is real. The question is whether it requires converting our most productive farmland, or whether better-engineered solutions can achieve both goals. We should deploy as much solar as possible while minimizing irreversible impacts on strategic agricultural resources and surrounding communities.
Engineering innovation can reduce land requirements, minimize disturbance, improve community acceptance, and preserve future options. Solar projects should be evaluated using a broader set of measures.
- Acres required and acres disturbed per megawatt
- Amount of prime cropland affected
- Agronomic reversibility after decommissioning
- Community acceptance and farmer involvement
- Environmental resilience and long-term land-use flexibility
Make stewardship the benchmark
The next generation of solar projects should compete not only on cost and energy production, but also on land stewardship. Technologies that reduce land consumption, preserve agricultural capability, minimize community impacts, and maintain the ability to restore land to food production should become the new benchmark for sustainable solar.
