U.S. communities seek to curb data center growth as AI buildout expands
Communities resist data centers

Local resistance to the rapid expansion of AI-linked data centers is moving onto ballots across the U.S. on Election Day. Voters in 10 states are weighing measures that could delay, restrict or block new projects, highlighting rising concerns over electricity use, water demand and health risks near residential areas.

Highlights

  • Voters in 38 U.S. jurisdictions are considering at least 41 ballot measures to limit or regulate data center development due to environmental and health concerns.
  • Ohio faces 21 ballot proposals affecting data centers, with potential restrictions likely redirecting, not cancelling, future projects amid ongoing political and community opposition.
  • Despite local resistance, U.S. data center capacity under construction is projected to increase 48% from December 2025 to June 2026, with projects ongoing, including Amazon’s $2 billion Sunbury investment at risk.

Ballot measures test data center expansion

As reported by Reuters, voters in 38 local jurisdictions are considering at least 41 measures tied to data center development, with proposals ranging from new operating requirements to outright limits on construction. Their presence on ballots follows petition drives and other support thresholds in many states, pointing to broadening political resistance as developers add capacity to support AI applications.

Ohio stands out as one of the country's fastest-growing data center markets and the state with the largest number of related ballot questions. Ballotpedia says voters in more than a dozen Ohio jurisdictions are set to weigh 21 proposals alongside Tuesday's midterm elections.

Jessica Baker, an organizer with advocacy group Conserve Ohio, says opposition is drawing support from both Democrats and Republicans. She says residents are focused on the heavy electricity and water demands of data centers and remain concerned about possible health effects near communities, including asthma risks for children, even when developers propose to generate power on site through gas turbines or nuclear reactors.

Industry growth continues despite local pushback

If Ohio voters approve restrictions, developers are likely to redirect projects to other markets rather than cancel them altogether, according to Baron Fung, who leads IT infrastructure research at Dell'Oro Group. He says the sector is already dealing with other constraints, including long waits for grid connections and rising construction costs.

Recent construction data indicates the backlash has not yet materially slowed the industry's broader expansion. John McWilliams, head of data center insights at Cushman & Wakefield, says U.S. data center capacity under construction rises 48% between December 2025 and June 2026, measured in gigawatts, and adds that projects continue moving forward in many areas despite friction in some jurisdictions.

The ballot fights are also drawing attention from major technology companies. In Sunbury, near Columbus, a proposal to ban data centers using more than 25 megawatts of power could disrupt Amazon's proposed $2 billion project, while the company says it remains focused on working with residents and officials and does not comment on whether the wider ballot initiatives will alter its expansion plans.

Our earlier article on U.S. AI data center expansion explained that many planned projects are running into mounting obstacles, from higher financing costs and construction delays to tightening power availability. We also noted that pushback from local communities and regulators is increasingly forcing developers to secure their own energy supply, adding another layer of risk to ambitious buildout plans.
