A sprawling wind farm — capable of generating enough electricity to power 100,000 homes — at the northern edge of Nebraska.

These projects — and hundreds of others — will never get built in the United States. They were blocked and ultimately killed by a regulatory sea-change that has reshaped how local governments consider and approve energy projects. One by one, counties and municipalities across the country are passing laws that heavily curtail the construction of new renewable power plants.

These laws are slowing the energy transition and raising costs for utility ratepayers. And the problem is getting worse.

The development of new wind and solar power plants is now heavily restricted or outright banned in about one in five counties across the country, according to a new and extensive survey of public records and local ordinances conducted by Heatmap News.

“That’s a lot,” Nicholas Bagley, a professor at the University of Michigan Law School, told us. Bagley said the “rash of new land use restrictions” owes partly to the increasing politicization of renewable energy.

Across the country, separate rules restrict renewables construction in 605 counties. In some cases, the rules greatly constrain where renewables can be built, such as by requiring that wind turbines must be placed miles from homes, or that solar farms may not take up more than 1% of a county’s agricultural land. In hundreds of other cases, the rules simply forbid new wind or solar construction at all.

Even in the liberal Northeast, where climate concern is high and municipalities broadly control the land use process, the number of restrictions is rising. At least 59 townships and municipalities have curtailed or outright banned new wind and solar farms across the Northeast, according to Heatmap’s survey.

Even though America has built new wind and solar projects for decades, the number of counties restricting renewable development has nearly doubled since 2022.

When the various state, county, and municipality-level ordinances are combined, roughly 17% of the total land mass of the continental United States has been marked as off limits to renewables construction.

These figures have not been previously reported. Over the past 12 months, our energy intelligence platform Heatmap Pro has conducted what it believes to be the most comprehensive survey of county and municipality-level renewables restrictions in the United States. In part, that research included surveys of existing databases of local news and county laws, including those prepared by the Sabin Center for Climate Change Law at Columbia University.

But our research team has also called thousands of counties, many of whose laws were not in existing public databases, and we have updated our data in real time as counties passed ordinances and opposed projects progress (or not) through the zoning process. This data is normally available to companies and individuals who subscribe to Heatmap Pro. In this story, we are making a high-level summary of this data available to the public for the first time.

Restrictions have proliferated in all regions of the country.

Forty counties in Virginia alone now have an anti-renewable law on the books, effectively halting solar development in large portions of the state, even as the region experiences blistering electricity load growth.

These anti-solar laws have even begun to slow down energy development across the sunny Southwest. Counties in Nevada and Arizona have rejected new solar development in the same parts of the state that have already seen a high number of solar projects, our data show. Since President Trump took office in January, the effect of these local rules have become more acute — while solar developers could previously avoid the rules by proposing projects on federal land, a permitting slowdown at the Bureau of Land Management is now styming solar projects of all types in the region, as our colleague Jael Holzman has reported.

In the Northeast and on the West Coast, where Democrats control most state governments, towns and counties are still successfully fighting and cancelling dozens of new energy projects. Battery electricity storage systems, or BESS projects, now draw particular ire. The high-profile case of the battery fire in Moss Landing, California, in January has led to a surge of local opposition to BESS projects, our data shows. So far in 2025, residents have cited the Moss Landing case when fighting at least six different BESS projects nationwide.

That’s what happened with Jupiter Power, the battery project proposed in Nassau County, Long Island. The 275-megawatt project was first proposed in 2022 for the Town of Oyster Bay, New York. It would have replaced a petroleum terminal and improved the resilience of the local power grid.

But opposed residents began attending public meetings to agitate about perceived fire and environmental risks, and in spring 2024 successfully lobbied the town to pass a six-month moratorium on battery storage systems. The developer of the battery storage system, Jupiter Power, announced it would withdraw after the town passed two consecutive extensions to the moratorium and residents continued agitating for tighter restrictions.

That pattern — a town passes a temporary moratorium that it repeatedly extends — is how many projects now die in the United States.

The Nebraska wind project, North Fork Wind, was effectively shuttered when Knox County passed a permanent wind-energy ban. And the solar project south of Columbus, Ohio? It died when the Ohio Power Siting Board ruled that “that any benefits to the local community are outweighed by public opposition” to the project, which would have generated 70 megawatts, enough to power about 9,000 homes.

The developers of both of these projects are now waging lengthy and expensive legal appeals to save them; neither has won yet. Even in cases where the developer ultimately prevails against a local law, opposition can waste years and raise the final cost of a project by millions of dollars.

Our Heatmap Pro platform models opposition history alongside demographic, employment, voting, and exclusive polling data to quantify the risk a project will face in every county in the country, allowing developers to avoid places where they are likely to be unsuccessful and strategize for those where they have a chance.
