ICLEI Case Studies

The ICLEI Case Study series highlights the role of ICLEI Members and other local governments as key drivers and implementers of urban sustainable development across the globe by illustrating successful approaches, innovative models and transferable good practices in the field of urban development and sustainability initiatives. Further, ICLEI Case Studies analyse the lessons learned, the replication potential, and the costs and financing of the given initiative.

IRENA-ICLEI Case Studies series (No. 155) - Renewable Energy in Cities 

Renewable Energy Policy in Cities: Selected Case Studies

These case studies were identified and selected for a global study by ICLEI-Local Governments for Sustainability on behalf of IRENA (International Renewable Energy Agency) to illustrate how local governments can support a transition to Renewable Energy. The city cases in focus span five different continents and are from the following countries: Australia, Brazil, China, India, Germany, Sweden, and United States.

The case studies portray a broad mix of what local governments can do to enhance the deployment of Renewable Energy in their city. Below, you may find an overview of the themes and case studies, and links to download the digital publications.
