International cooperation has always been a high priority at AEE INTEC. Since the beginnings of our institute, we have looked beyond national borders and developed and implemented sustainable solutions in numerous projects at European level and in cooperation with international organizations such as UNIDO and ADA. These partnerships have taken us from Europe to Asia via Africa to Latin and South America. The scientific exchange that we maintain with these collaborations is always based on communication as equals and joint learning. From this openness and curiosity, we have gained valuable impulses and insights for our own research. In this issue, we share insights into our international activities and reflect on how they enrich our work and our understanding of research in a global environment.
