Results of regular representative surveys on environmental awareness in Germany show, that one of the most important environmental tasks for the respondents is to reduce CO2 emissions and switch to renewable energies. They consider themselves as well-informed about environmental knowledge, but only a few change their consumption habits. Thus, transferring knowledge from complex transformation processes such as mobility and energy systems, seek for innovative mechanisms. The Sustainable Living Lab Mobility2Grid develops sustainability innovations by using electric vehicles’ batteries as storages for renewable energies in a decentralized urban micro smart grid. Transferring its results into society is a key task of M2G. Hence, this paper focuses on the question: What knowledge about mobility and energy transition can and must be imparted trough target group-oriented training programs? The case study is, from a methodical perspective, approached as an action research case, and hence aims at discovery, interpretation, reflection and insights. Primary data was gathered from a qualitative survey with participants after each training session (module). In total nine trainings with employees of different institutions and industries such as energy, mobility, city cleaning, transport federation, science and education were carried out. The study shows that a technical understanding, fundamental connections about the topic of electro mobility and micro smart grids, an improved understanding of the electro mobility`s historical development and last but not least, an outlook and future ideas of electro mobility were key categories of learning outcomes.
