History

Historical Context

After New York City adopted citywide energy-efficiency rules for public buildings in 2005, which spurred retrofits and set a benchmark for data-center power use, Chicago introduced a 2024 moratorium on new data-center permits. Mayor Brandon Johnson and Alderman Gilbert Villegas aim to curb expansion of the city’s 39 existing centers. The IEA estimates data centers consumed about 415 TWh, roughly 1.5 % of global electricity in 2024.
