Sen. Bernie Sanders has introduced a bill in the Senate to impose a national moratorium on the construction or upgrading of new AI data center projects until Congress passes AI legislation that ensures the safety and prosperity of the American people. This comes as major tech companies, including Amazon, Microsoft, Google, and OpenAI, are investing billions in building out the infrastructure needed to train and run their competing AI models. The bill defines an AI data centre as a facility used to develop or operate AI models at scale, or one with a peak power load exceeding 20 megawatts. It also includes policies to prevent job displacement and share the economic gains from AI with the American public. The chances of this proposal becoming law are uncertain under the current administration.
