Lawmakers in Maine this week passed a statewide a temporary suspension on new data centres, marking the first time a US state has officially moved to halt the rapid expansion of the infrastructure that is powering the artificial intelligence (AI) revolution. The legislation comes as the AI industry faces growing pushback over its massive environmental footprint and its impact on local utility bills even as other states mull to introduce similar laws.
A ‘first of its kind’ ban in America and why there is pushback against data centres
The Maine bill, which passed through both Democratic-controlled chambers, places an 18-month pause on any new data centres requiring more than 20 megawatts of power, according to a report by The New York Times. During this time, a state study group will investigate the long-term effects of these facilities and suggest permanent “guardrails.”There has been an opposition against building data centres because they consume vast amounts of electricity to run high-powered processors, which can drive up electricity prices for regular households. They also consume huge quantities of water to cool the heat generated by the servers, purportedly impacting household in the vicinity of these massive structures.
Why Maine’s move may fuel political tension in America
The move puts Maine on a collision course with the federal government, and may prompt other states to follow the suit. The Trump administration, however, has taken a firm stance against state-level tech regulations, arguing that American companies must be “free to innovate” to win the global AI race against adversaries.President Trump has previously threatened to sue states that pass laws restricting AI growth, and withhold federal funding from states that create ‘cumbersome’ regulations.While Maine has hit the “pause” button, other states are split. New Hampshire recently rejected a similar moratorium, while Massachusetts leadership has expressed a desire to build more AI infrastructure to stay economically competitive.Meanwhile, In California, legislators enacted regulations for AI companies last year. Governor Gavin Newsom followed up with an executive order that added new requirements for privacy and transparency.
What it means for tech companies expanding data centre footprint
Tech giants like Google, Microsoft and those operating in AI and hyperscale cloud services, will face a complete pause on setting up new large data centers (20MW+) in Maine until at least November 2027. Notably, there are no major data centres in the US state.
