Lawmakers in the US state of Maine have approved a bill to impose what would be the nation’s first statewide moratorium on large, energy-intensive data centers, reflecting growing political resistance over concerns about power consumption, water use and electricity costs.

The Democratic-controlled Legislature on Tuesday passed the measure and sent it to Governor Janet Mills, who is running for the US Senate. The proposed law would halt development of large-scale data centers for more than a year and establish a special council to help local authorities assess future projects.

Although Maine is not a major hub for hyperscale data centers, recent proposals triggered strong local opposition, accelerating the bill’s passage. The move highlights rising resistance to such facilities, even as they receive support from the administration of President Donald Trump and various state leaders who view them as vital for economic growth and competition in artificial intelligence.

Supporters of the moratorium argue that the benefits of data centers have not been proven in terms of electricity costs, water usage or local economic gains. However, industry representatives warn the measure could discourage investment, limit job creation and hinder workforce development.

Community groups backing the legislation say it is intended to ensure greater public input and transparency in decision-making.

Similar moratorium proposals have been introduced in several US states, though none had previously cleared a legislative chamber.
