Summary

Highlight any text to annotate
This bill would impose a freeze on the construction and expansion of artificial intelligence data centers in the United States until Congress passes comprehensive AI safety legislation. The moratorium applies to large computing facilities with power capacities exceeding 20 megawatts or facilities using advanced cooling systems typical of AI operations. Before the freeze can be lifted, lawmakers must enact laws establishing federal safety reviews for AI products, policies to prevent job displacement, protections against increased utility costs and environmental harm, community approval rights for new facilities, prohibitions on government subsidies, and requirements for union jobs with prevailing wages. The bill also requires the Secretary of Energy to issue quarterly public reports on data center operations, including details on water usage, emissions, wages, and subsidies, with authority to conduct inspections and issue subpoenas for compliance. Additionally, the legislation restricts U.S. exports of computing hardware used for AI development to countries that lack comparable AI safety regulations. The bill does not specify a timeline for when the moratorium would end, leaving that determination contingent on future legislative action.
