Two influential politicians, Senator Bernie Sanders and Rep. Alexandria Ocasio-Cortez, are proposing a ban on new data centers with peak power loads exceeding 20 megawatts. The proposed legislation would halt the projects until Congress approves comprehensive AI regulation. The lawmakers also aim to require the US government to review and certify models before they are released and limit the environmental impact of data infrastructure. However, this could be difficult due to significant political influence by AI companies and potential conflicts with China.
