Maine is set to impose the nation’s first statewide moratorium on energy-hungry data centers in a sign of growing political opposition to tech giants’ massive structures that have stoked fears about blackouts, rising electricity bills and voracious water needs.

The legislation arose in a state that isn’t necessarily a destination for the computer-stocked warehouses that power artificial intelligence, but a couple of proposals there generated intense community backlash and helped propel a measure quickly through the state’s Democratic-controlled Legislature. Lawmakers on Tuesday approved sending the bill to Gov. Janet Mills, a Democrat who is running for U.S. Senate.

It’s the latest sign that increasingly stiff opposition at the local level is gaining a foothold higher up the political ladder. Tech giants and the data centers they are building have high-level support from President Donald Trump’s administration and many governors, who see them as economic engines and essential for winning the artificial intelligence race with China, even as voters raise concerns about the enormous amount of power data centers use. Analysts also warn of the possibility of blackouts in the mid-Atlantic grid in the coming years.
