The report “Inspiring Visions of a Sustainable Energy Future’ was prepared to document the activities of the 100% Renewables Cities and Regions Roadmap project, particularly those that took place at various international workshops, including special sessions, discussions, and site visits. The purpose of these workshops and visits was to encourage the exchange of ideas and knowledge across the various project cities and regions, as well as learn about innovative ideas from other parts of the world, and spread awareness about cutting-edge technologies that could be considered in an urban or regional context.
