Senator Bernie Sanders plans to introduce a bill that would impose a nationwide moratorium on building or upgrading data centers used for artificial intelligence until Congress enacts laws meant to protect the public from AI risks. Representative Alexandria Ocasio-Cortez is preparing a similar measure for the House.

What the bill would do

The proposed law places an open-ended pause on new and expanded data centers that are dedicated to AI work, using physical criteria to define which facilities are covered, including sites with energy loads above 20 megawatts. The moratorium stays in place until lawmakers pass rules that address several concerns:

  • Preventing data centers from worsening climate change and harming the environment.
  • Stopping data center-driven spikes in household electricity bills.
  • Ensuring AI products do not harm worker health and well-being, privacy, civil rights, or broader human safety.
  • Forcing tech companies to share AI-generated wealth with the public.
  • Banning export of key computing hardware to countries that lack comparable protections.

The bill even explicitly calls out prominent AI executives and companies as examples of actors who have profited from the technology while sounding alarms about its rapid pace of change.

Why people are worried

Local communities and environmental groups have raised repeated objections to the rush of data center construction. Complaints fall into a few buckets: rising electricity bills, heavy water use, land and community impacts, and general unease about handing the infrastructure for powerful AI to private firms.

Polling shows a sizable share of the public sees data centers as an environmental and local quality-of-life problem. Community pushback has already stalled or canceled a large amount of planned development. One recent tally found billions of dollars in projects delayed or dropped in a single quarter because of opposition.

Local and state action

Dozens of cities and counties have enacted local moratoriums. At least a dozen state legislatures have considered or introduced statewide pauses, with proposals appearing in states across the country. Some bills are driven by Democrats, others by Republicans, and a few have cross-party support.

Politics and players

Sanders has framed the pause as a chance to make sure AI benefits working families, not just wealthy executives. Supporters include environmental groups that helped press Congress earlier with a broad letter calling for a moratorium.

Concern about data centers is not confined to one side of the political aisle. Several conservative figures and some Republicans in Congress have also criticized the build-out, and a bipartisan pair of senators recently introduced legislation aimed at shielding customers from utility rate increases tied to data centers.

Florida’s governor has been especially vocal about both AI risks and the impact of data centers, proposing state-level protections that would limit subsidies and restrict data centers from raising electricity costs. Some of those state proposals advanced in legislatures but stalled elsewhere.

How industry and the White House are responding

Big tech and the White House have acknowledged the bad optics around data center growth. Industry leaders agreed to a nonbinding statement about covering infrastructure and energy costs tied to data centers, an effort critics say is mostly symbolic. Observers note that some of the key commitments, like absorbing extra costs, are not fully within the control of companies or the administration.

The industry warns that a federal moratorium could have serious downsides, including reduced internet capacity, slower critical services, lost high-wage jobs, and lower local tax revenues. Trade groups say they want to work with communities and policymakers to find solutions that let the industry continue while protecting families.

Where this leaves us

The bill is unlikely to clear Congress quickly, given strong federal and industry support for rapid AI deployment, and the money tech companies are poised to spend in Washington. Still, the proposal matters because it brings together environmental, labor, and AI safety concerns in a single national push.

Whether the pause becomes law or not, the debate is shifting. More cities, states, and activists are treating data centers as a public policy issue, not merely a real estate or tech story. That shift could shape how and where powerful AI systems get built in the coming years.
