Chicago’s airports, libraries and water-purification plants will soon be running on 100% clean energy thanks to a deal announced by Mayor Lori Lightfoot to shift all city-wide operations to renewable sources by 2025, making it one of the largest US metropolitans to pledge such a move.  

The city signed an energy supply agreement with retail electricity supplier Constellation, with an initial five-year term beginning in January 2023, the mayor’s office said Monday in a statement. The agreement will also allow Chicago to partially source it large energy needs from a solar project that’s currently being developed by Swift Current Energy.
