Earth Hour

Cook County will turn off its non-essential lights March 25 to commemorate Earth Hour and call attention to climate change. The Cook County Department of Facilities Management will save energy – and send a message about the role all of us can play in cutting harmful greenhouse gas emissions – by turning off lights from 8:30 p.m. to 9:30 p.m. at the County Building, the Dunne Administration Building and nine other facilities located in Chicago and five other municipalities throughout Cook County.

Want to do more to reduce your carbon footprint? You can start by observing Earth Hour in your home. In addition, the U.S EPA has suggestions for easy changes you can make in your daily life.

Cook County is also a resource. For information on smart energy use, visit our website or contact Sarah Edwards at
