More than 1,000 data centers are moving toward American neighborhoods

More than 1,000 data center proposals are pending across the United States. That count comes from a Harvard researcher who studies the relationship between data centers and energy and has tracked how local governments respond to these projects. The surge is driven by demand for artificial intelligence, which needs vast computing capacity to run.

That number sets the stakes. It does not mean every proposal gets built. Across the country, towns are pushing back, and winning, by using tools that shape the decision before a single wall goes up.

Why the pushback is happening

The tech industry makes a familiar promise: jobs, economic revitalization, and growth. So far, according to the Harvard researcher, those benefits are overshadowed by more visible harms.

The harms are not abstract. Nearby residents experience higher air pollution and excess noise. Data processing uses large amounts of water to cool buildings and equipment. And electricity prices continue to outpace inflation, driven in part by the costly infrastructure needed to power these facilities. Consumer Reports has documented the impact of AI data centers on electric bills and water use.

Federal policy adds fuel. The Trump administration has identified data center build-out as a strategic priority and signaled that some federal regulations may be eased. That leaves the real fight at the local level, where residents live with the consequences.

Noise, water draw and power bills land next door

A building-biology lens asks one question first: where does the harm enter your living space? For a data center, the pathways are specific and measurable.

Noise. Data centers run cooling fans and chillers 24 hours a day. That produces a constant low hum that does not stop. Residents near a hyperscale facility in Dowagiac, Michigan, filed a class-action lawsuit over the round-the-clock noise. Chronic noise is more than a nuisance. Steady nighttime sound disrupts sleep and elevates stress, and long-term environmental noise is linked to higher cardiovascular risk. The source-control fix is distance and enforceable decibel limits at the property line, written into the permit before approval.

Air pollution. Large data centers keep backup diesel generators on site to guard against outages. When those generators run or undergo testing, they emit fine particulate matter and nitrogen oxides, the same pollutants as any diesel engine. Researchers at the Harvard T.H. Chan School of Public Health have analyzed the air pollution and health risks tied to AI data center growth. Fine particulate matter reaches deep into the lungs and is tied to asthma, heart disease, and premature death. The pathway runs straight from the generator stack to nearby homes.

Water. Cooling equipment consumes large volumes of water. The Environmental and Energy Study Institute has documented how much water data centers use, and companies rarely disclose exact figures. That draw competes with household and agricultural supplies. The water pathway is why one Michigan utility chose to cut it off entirely, more on that below.

Rising bills. When a utility builds new power plants and transmission lines to serve a data center, the cost can spread to every customer. A higher electricity bill is a health stressor in its own right. Families under financial strain may cut back on cooling during heat waves or heating during cold snaps, choices that raise the risk of illness for older adults, infants, and people with chronic conditions.

The common thread is source control. Preventing an exposure is far more effective than managing it after the building runs.

The community toolkit that works

Local governments across the U.S. are trying to reduce these harms, and several tools have proven effective.

Moratoriums. A short-term pause on permitting gives a community time to write real rules, on location, electricity use, water conservation, and noise buffering, before any project moves forward. Merrillville, Indiana, about 40 miles southeast of Chicago, adopted a one-year moratorium. Town council president Rick Bella said the town wanted to “evaluate real-world impacts and learn from a project developing right next door before determining what may or may not be appropriate for Merrillville.”

Utility service halts. In April 2026, the Ypsilanti Community Utilities Authority near Detroit passed a yearlong halt on the “delivery, commitment, reservation, extension, or approval of water and sewer services” for data centers. The move blocked a data center under development by the University of Michigan and Los Alamos National Laboratory. No water and sewer, no facility. Control over a single resource gave a local body the power to say no.

Ballot measures. Towns across Ohio, Wisconsin, Maryland, Nevada, and California have put data center questions directly on local ballots. Through these referendums, voters weigh in on construction bans, tax incentives, and zoning ordinances, taking the decision out of a single hearing room and into the general electorate.

Elections. Voters hold officials accountable. In April 2026, voters in Festus, Missouri, removed several City Council members after they approved a new data center despite resident pushback. In Sunbury, Ohio, local officials only considered a moratorium after witnessing the scale of public protest.

Petitions and coalitions. Town hall discussions, community coalitions, public petitions, and even farmers’ unions have all played a role. In New Jersey, 60 groups called on the governor to pause all AI data center projects.

The pushback is not guaranteed to win

The tools work, but the opposition has power too, and it does not always come from the tech companies alone.

State governments can strip local control. In 2025, West Virginia passed a bill that reduces local governments’ zoning and regulatory powers over data centers and microgrids. A similar bill in New Hampshire’s legislature was defeated in May 2026. In Hood County, Texas, officials rejected a six-month moratorium after a state senator urged the state attorney general to intervene.

Tech companies also litigate. Data center developers sued Saline Township, Michigan, and Chatham County, North Carolina, seeking to overturn local zoning decisions and proceed with construction. A lawsuit can pressure a small local government with limited legal resources to back down.

Public attitudes, notably, have remained largely nonpartisan. The New York Times has reported that opposition crosses political lines. That matters, because it means a broad coalition of residents can form regardless of party.

What you can do

You do not need a lawyer to be effective. You need to act early and push for specifics.

Ask for a moratorium before a project is on the table. A pause is easiest to pass before a specific developer has money committed. Merrillville used its year to write rules first.

Demand measurable thresholds in writing. Push for a maximum decibel limit at the property line, mandatory setbacks from homes, a daily water-use cap in gallons, and limits on generator testing hours. A promise at a podium is not a permit condition.

Follow the water and sewer. Ask your local utility authority whether it will commit service to the facility. As Ypsilanti showed, utility service is a chokepoint residents can influence.

Put it on the ballot. If your officials will not act, a referendum takes the decision to every voter in town.

Vote accordingly. Festus voters removed council members over a data center approval. Officials who ignore residents face that same accountability.

The buildout is set to continue, AI demand keeps pushing new proposals into new towns. Where each one lands, and under what conditions, is still open. The communities that act early, and write numbers into their ordinances, are the ones deciding the outcome.
