President Biden signed an executive order to fast-track large-scale artificial intelligence (AI) infrastructure in the United States, prioritizing national security and climate change. The order directs the Department of Defense and the Department of Energy to lease federal sites for the private sector to build frontier AI infrastructure. Biden emphasized the importance of building AI infrastructure in the US for national security and to prevent dependence on other countries. The order also requires developers to pay for the construction and operation of AI data centers and bring clean power generation to match their capacity needs. The Interior Department will identify suitable lands for clean energy development to support data centers on government sites.
