Data centers are becoming a public health flashpoint — and a political one

The explosive growth of hyperscale data centers — the massive facilities powering AI infrastructure — is triggering a public health backlash that's now spilling into the 2026 midterm elections. Communities from Page, Arizona to rural Ohio are pushing back against proposed and existing centers, citing concerns over air pollution from diesel generators, water contamination from cooling chemicals, noise exceeding 90 decibels, light pollution, and rising local temperatures from so-called "data heat islands."

The political fallout is cutting across party lines. Two-thirds of Americans oppose new data center construction, and the issue has become a liability for politicians — including some Republicans — who previously championed the facilities as economic wins. In Ohio alone, more than a dozen local referendums on data center construction will appear on November ballots.

By the Numbers:

• ~1,300 estimated annual deaths from data center emissions by 2030
• $20B+ projected annual public health burden by 2028
• ~1,400 data centers currently operating in the U.S., with 2,000+ more planned
• $2.5B in state and local tax breaks awarded to data centers in Ohio over the past decade
• 55–67% of Ohio adults oppose data center construction or view its environmental impact negatively

Why it matters: As AI infrastructure demands surge, the health and environmental costs of data centers are becoming impossible to ignore. With research still in early stages and construction decisions being made now, communities and policymakers face pressure to act before the full scope of harm is understood.
