Policymakers in multiple countries are taking decisive action to restrict new data centre development, reflecting mounting concern that the infrastructure powering the artificial intelligence revolution is creating unsustainable pressures on energy systems, water resources and surrounding communities. From New York to Ireland to the Netherlands, governments are implementing freezes, moratoriums and outright prohibitions on large computing facilities, marking a significant shift in how nations are managing the physical demands of the digital economy.
New York has become the first American state to enforce a comprehensive moratorium, with Governor Kathy Hochul directing a one-year suspension on construction of data centres consuming 50 megawatts or more of electricity. During this freeze period, the state's Department of Environmental Conservation will refrain from issuing new discretionary permits while officials work to establish standardised criteria for evaluating the environmental consequences of such installations. This approach gives the state time to develop a more systematic framework for assessing whether new facilities can operate sustainably within existing infrastructure.
Maine's political leadership encountered obstacles in advancing similar restrictions. Governor Janet Mills vetoed bipartisan legislation that would have created an 18-month moratorium covering data centres exceeding 20 megawatts in capacity, which would have represented the first statewide ban of this kind in the United States. While Mills expressed philosophical support for a temporary freeze, she opposed specific provisions in the bill that failed to provide an exemption for a particular development planned in the Town of Jay, demonstrating how local economic interests can complicate broader policy objectives.
California residents have gone further than any US jurisdiction by voting for a permanent prohibition. Monterey Park became the first American city to ban data centres entirely through a popular ballot measure in June 2026, following sustained public opposition to a proposed facility. The community had previously imposed a one-year moratorium in 2019, then extended restrictions through at least 2030 in April 2025, before citizens ultimately decided to eliminate the possibility altogether. This escalating pattern reflects deepening frustration among residents about the tangible impacts these installations create in their neighbourhoods.
Europe's experience offers different models for managing data centre expansion. The Netherlands implemented a hyperscale ban in 2022 that concentrates large facilities to just two designated national locations, thereby preventing the dispersal of infrastructure across the country. However, this policy has proven flexible in practice; Microsoft secured approval in January 2026 for a project designed as three separate towers, each individually beneath the regulatory size threshold, demonstrating how determined companies can navigate around restrictions through creative structural arrangements.
Ireland's approach illustrates both the severity of grid strain and the possibility of resolution. The country's grid operator effectively froze new data centre connections around Dublin beginning in 2021 after assessments showed these facilities were overloading electrical infrastructure. After more than four years of restriction, the freeze ended in December 2025, though with a significant requirement: new operators must now develop their own on-site power generation capacity rather than relying entirely on the national grid. This conditional lifting represents a pragmatic solution that allows expansion while transferring infrastructure responsibility to individual developers.
For Southeast Asian nations, particularly Malaysia, Singapore and Thailand, these global trends carry important implications. The region has positioned itself as an attractive alternative to overcrowded Western markets for data centre investment, offering lower costs, strategic geographic location and growing digital infrastructure. However, the restrictions emerging in developed economies suggest that regional governments should establish clear environmental and infrastructure standards now, before facility development accelerates beyond the capacity of local power and water systems to sustain.
The fundamental tension driving these restrictions is straightforward: artificial intelligence requires enormous computational power, and each data centre consumes electricity equivalent to a small city. In jurisdictions already operating at or near maximum grid capacity, adding major new facilities creates cascading problems. Communities near data centres report increased electricity costs as demand spikes, depleted groundwater from cooling operations, and noise pollution from mechanical systems running continuously. As AI adoption spreads and training models grow more sophisticated, these demands will only intensify.
Malaysian policymakers should monitor how other nations balance economic opportunity against environmental sustainability. Data centres bring significant investment, employment and tax revenue, making them attractive to development authorities. Yet the experiences from New York, Maine, California and Ireland demonstrate that communities eventually rebel when the environmental and infrastructure costs become visible and measurable. Strategic planning now—establishing designated zones, requiring environmental impact assessments, and mandating renewable power for new facilities—could allow Malaysia to capture AI investment while avoiding the backlash that other regions are experiencing.
The global mosaic of restrictions also reveals how artificial intelligence development will increasingly depend on jurisdictions willing to absorb these infrastructure costs. As developed nations tighten controls, investment and facility construction will shift toward countries with more permissive regulatory environments and cheaper electricity, particularly in Southeast Asia and South Asia. This dynamic could accelerate regional data centre development in coming years, making it critical for Malaysian authorities to establish frameworks now that balance growth with sustainability rather than imposing restrictions retroactively after communities have already suffered environmental damage.
