The development and dissemination of new digital hardware and applications has been taking place at enormous speed for decades. However, what about resource efficiency and sustainability of innovations in the field of information technology and computing centers? This question is at the heart of the ENRICH research project, which investigates the impact of digitization on energy and resource consumption in German State of Baden-Württemberg. To this end, ENRICH analyses issues such as the latest megatrends in IT technologies, sustainable procurement, and the development of various energy efficiency measures. DIALOGIK's contribution focuses on the user perspective and addresses the role of users in the megatrends of digitization and at the operational level of digital infrastructures.
