President Joe Biden will issue an executive order on Tuesday to provide federal support to address massive energy needs for fast-growing advanced artificial intelligence data centers, the White House said. The order calls for leasing federal sites owned by Defense and Energy departments to host gigawatt-scale AI data centers and new clean power facilities - to address enormous power needs on a short time frame. Biden said the order will "accelerate the speed at which we build the next generation of AI infrastructure here in America, in a way that enhances economic competitiveness, national security, AI safety, and clean energy."
