Lawmakers in Maine have approved a first-in-the-nation bill to temporarily halt the construction of large-scale artificial intelligence data centers, signaling growing concern over the rapid expansion of energy-intensive digital infrastructure.

The legislation would impose an 18-month moratorium on building data centers that consume more than 20 megawatts of power. If signed into law by Gov. Janet Mills, the measure would create a statewide pause while officials evaluate the long-term impacts of such developments.
During the moratorium, a council made up of government officials, industry experts and other stakeholders would be tasked with developing recommendations and guidelines for future data center construction. The goal is to better understand the economic, environmental and social implications tied to the fast-growing sector.
The bill’s passage reflects a broader shift in public sentiment, as communities and policymakers increasingly question the pace and scale of AI-driven infrastructure development.
Data centers, particularly those supporting artificial intelligence, require vast amounts of electricity and water to operate. Critics argue that their rapid expansion could strain local utilities and natural resources.
A typical AI data center can consume as much electricity as 100,000 households, raising concerns about grid capacity and sustainability. Projections from the International Energy Agency suggest that by 2030, U.S. data centers could consume more electricity than several major industrial sectors combined, including cement, steel and automotive manufacturing.
In addition to energy use, these facilities often rely on significant water resources for cooling systems, which can place added pressure on local water supplies. Environmental advocates also point to increased emissions and potential air quality impacts tied to power generation needed to support these operations.
The Maine bill does not permanently ban data center construction but instead creates time for a more measured approach. Supporters say this allows for a balanced evaluation rather than an outright rejection of emerging technologies.
Maine’s action comes amid similar efforts across the United States, where multiple states and municipalities are exploring ways to regulate data center growth.
Local resistance has already emerged in several communities. In Port Washington, Wisconsin, voters recently approved a measure requiring public approval for large tax incentives tied to data center projects. Meanwhile, in Festus, Missouri, local elections saw incumbents lose their seats following public backlash over data center approvals.

At the federal level, tensions are also rising. President Donald Trump has reportedly threatened legal action against states that attempt to restrict AI-related development, highlighting the growing divide between economic expansion and regulatory oversight.
Despite uncertainty over whether Mills will sign the bill, its passage underscores a broader trend: increasing scrutiny of AI infrastructure and its real-world impacts.
Supporters argue that a temporary pause offers a critical opportunity to weigh the benefits of technological growth against potential risks, including environmental strain, economic trade-offs and community disruption.
As AI continues to drive demand for large-scale data centers, Maine’s approach may serve as a model for other states seeking to balance innovation with responsible development.
