**Widespread local opposition to large AI-driven data centers, fueled by high electricity and water demands plus land-use impacts, has produced over 125 active municipal and township moratoriums across Ohio as of mid-September 2026.** Residents and groups like Conserve Ohio are pushing a constitutional amendment banning facilities over 25 MW peak load, collecting roughly 130,000–140,000 signatures toward a possible 2027 ballot after missing the 2026 deadline. Multiple communities will vote November 3 on local bans, zoning limits, or voter-approval requirements. State lawmakers have advanced study commissions and tax-break reforms but enacted no statewide pause, with polls showing 63–75% public support for restrictions. Upcoming catalysts include the November local results and continued legislative sessions, though a binding statewide moratorium before late 2027 remains uncertain given the ballot timeline and mixed economic views on outright bans versus targeted rules.
