Central to the WISIONS approach is the interaction between knowledge (about change) and action (for change). This approach is rooted in the Wuppertal Institute’s research tradition, which is centred on developing transformation processes aimed at shaping a climate-friendly and resource-efficient world. Under knowledge we make available the lessons learned about what works and what doesn’t work when it comes to effectively stimulating sustainable development for rural and peri-urban populations through the application of decentralised renewable energy solutions.
