On Tuesday (local time), Josh Shapiro, the Governor of Pennsylvania in the United States, signed an executive order introducing new regulatory stipulations for the construction of artificial intelligence (AI) data centers within the state. This move is poised to potentially curb the expansion of the AI sector. The fresh regulations mandate that relevant companies adhere to environmental protection and information transparency criteria, and secure approval from local communities. For example, companies are now required to bear the complete electricity expenses for data centers, with a substantial portion of the power being derived from clean energy sources.
