The System Innovation Lab is a joint project of Wuppertal Institute and the Centre for Social Investment and Innovation Heidelberg (CSI). It addresses young Europeans in government, the private sector and civil society with an energy focus. It is designed as an on-the-job training and coaching towards bringing System Innovations in the respective work contexts. The two one-week seminars offer learning about different perspectives on transforming energy systems in Europe and concrete concepts with which to develop, test and reflect on the success of prototypes for their particular job setting. The Lab's goal is to enable particpants to take their ideas to scale after this actual training and exploration phase is over.
