Ohio banned solar farms to protect its farmland but golf courses already took far more of it

In Ohio, a major political fight is happening over solar farms.

County officials have passed several bans. They want to protect local farmland. State lawmakers have also added new legal hurdles.

Even the U.S. Agriculture Secretary has weighed in.

Critics say big solar projects devour precious cropland and they want to stop them.

Now, a new industry map shows real acreage figures. The numbers raise a very uncomfortable question. Who is really threatening Ohio’s farms?

How a battle is being fought county by county

A 2021 Ohio law gave counties major new powers. It was championed by a Republican state senator. Counties can now ban most solar and wind projects outright. Protecting agriculture was central to this political pitch.

Richland County passed its own ban recently. Local commissioners cited a desire to keep the farming character. “They are very protective of farmlands,” an official explained.

One local group beat back a referendum to overturn the ban. They called themselves Richland Farmland Preservation.

This pattern is spreading fast across America. Local officials in Idaho and Wisconsin passed similar laws.

A 2025 report detailed these new local ordinances. It came from the Sabin Center for Climate Change Law at Columbia University.

The U.S. Agriculture Secretary amplified this argument nationally. She invoked prime farmland loss to fight New York’s solar approach.

Then she announced a major policy shift. Her agency would stop funding solar on productive farmland altogether.

What the map actually shows

How much farmland is solar actually taking?

The Solar Energy Industries Association recently released a land-use map. It provided a very clear answer for Ohio.

Solar panels cover less than one-seventh of 1% of prime farmland. About 31 square miles of Ohio solar area overlap with prime farmland. That is a real number.

However, context matters enormously here.

Golf courses occupy more than 2.7 times that area. Suburban sprawl is an even bigger factor. Between 2014 and 2024, sprawl consumed five times more prime farmland.

Solar also sits on leased land.

Housing developments permanently destroy farmland. Solar does not destroy the soil. It allows the land to become arable again later. Housing developments simply do not offer that.

Corn fields already power cars

A lot of Ohio’s farmland already produces energy. It just does not flow into the electrical grid.

Ohio farmers harvested corn from over 3.1 million acres last year. About 40% of that corn becomes ethanol. The ethanol is blended into gasoline for cars.

A 2025 study by Cornell University looked closely at this land use.

Corn ethanol requires roughly 30 times more land per unit of energy than solar. Millions of acres already go to energy production. Yet, we see little protest from solar critics.

The farmland protection argument is being applied selectively. It looks less like a principled stand and more like a framing choice.

Rising electricity demand raises the stakes

The timing of these local bans is not neutral.

Ohio is facing fast growth in electricity demand. This growth pushes energy bills higher for everyone.

Solar and storage make up most new U.S. generating capacity. They accounted for 91% of additions in the first quarter.

An industry expert put the urgency plainly. “Gas plants take five to seven years to build,” he said. “We are still years away from new nuclear.”

Solar-plus-storage is available right now.

Local township commissioners do not always think about the regional grid. There is a gap between local decisions and regional needs.

County-by-county bans make this tension harder to resolve. Macro energy concerns rarely move the needle at the local level. The scale mismatch is very real.

Solar and farming do not have to be enemies

The loudest voices frame this as a strict choice. They say it must be farmland or solar. The evidence suggests otherwise.

In Knox County, a local farmer made a deal. He struck a sheep-grazing agreement with a solar project.

This is a working example of agrivoltaics. The land serves energy and agricultural purposes at the same time.

Madison County is running pilot studies too. They are testing how to grow forage crops between panel rows.

The Ohio Farm Bureau Federation is not calling for blanket bans. They want thoughtful local land-use planning. They want to weigh agricultural needs alongside energy priorities.

“Achieving a clean energy future does not have to be a choice,” an environmental advocate said.

Solar occupies a tiny sliver of prime farmland. It uses far less than golf courses or subdivisions.

The real question is about current policy. Are these laws actually protecting farms? Or are they just blocking one single land use? They seem to ignore other uses that cause permanent damage.
