Pennsylvania Gov. Josh Shapiro (D) will announce new stringent regulations on data centers on Tuesday, reversing some of his past policies while embracing more rigorous reviews of the projects that have angered residents throughout the state.

Shapiro, a Democrat up for reelection this year, plans to sign an executive order blocking any new data center project in Pennsylvania unless it meets new guidelines that limit electricity and water use.
