The US city of Chicago plans to run more than 400 public buildings, including City Hall and two international airports, with 100% renewable electricity.
Chicago says it is one of the biggest cities in the U.S. to make this commitment, which is expected to reduce the city’s carbon footprint by more than 290,000 metric tons each year. According to the U.S. Environmental Protection Agency, it’s equivalent to the emissions of 62,000 passenger vehicles.
The Illinois city has signed a new five-year clean energy deal with electricity supplier Constellation. As part of the agreement, Chicago’s two airports, its central library and its Jardine Water Purification Plant, the biggest water treatment plant in the world, will run partially on solar energy.
