As of January 1, 2025, the City of Chicago is sourced by 100% renewable energy! From O’Hare Airport to Harold Washington Library, all City buildings are part of this renewable energy transition. This is just the first step toward ensuring all electricity consumed in Chicago is sourced from clean, renewable sources by 2035.
