Beginning in 2010 Illinois State University and the Bloomington Normal community have participated in the observance of Earth Hour. Led by the World Wildlife Fund, Earth Hour has grown into a global phenomenon that has captured the world’s attention.
Each year since 2007, individuals, organizations, businesses and state and local governments have come together to show their support by turning off lights in homes, workplaces and at iconic landmarks such as the Empire State Building, the Las Vegas Strip and the Sydney Opera House. The 2010 event saw an estimated 1 billion participants from around the globe join together in raising awareness about climate change.
The Town of Normal, the City of Bloomington, and several area businesses observe the hour. At the Children's Discovery Museum and the Normal Theater, light was reduced. State Farm shut off lights at several of their corporate facilities in the area. The community's sister cities of Canterbury, England and Vladimir, Russia, also take part.
Illinois State community members are encouraged to participate on campus and at home by turning off non-essential lights and appliances on this night. On campus, the Association of Residence Halls observe Earth Hour.
