Illinois, known for its rivers, farmland, and endless skies, also has one of the fastest growing solar energy markets in the country. Communities are setting carbon reduction goals, incorporating green stormwater infrastructure into rainwater plans, and becoming more walkable, bikeable, and livable. The Sustainable Communities Initiative connects Illinois communities to University of Illinois scholars and students, bringing the latest research findings to decision-makers, and helping researchers understand and address Illinois' most pressing sustainability challenge.
