All of Chicagoโs Municipal Buildings Are Now Powered by 100% Renewable Energy
Each year, approximately 700,000 megawatt hours of electricity are expended to power Chicagoโs 411 municipal buildings. The beginning of 2025, however, signaled a major milestone in the cityโs efforts toward increased sustainability. As of January 1, all buildings owned and operated by the city are officially powered by 100% renewable energy, including OโHare International Airport, Harold Washington Library, 98 fire stations, and two of the worldโs largest water treatment facilities.
