05 | The Internet

The internet is the fastest growing infrastructures in the world and while it already shapes our everyday life, it's impact will still grow in the future. In this episode we try to give you a basic understanding of how the internet works and how it may be different from other large networked systems.

04 | Spatial (In)Justice

In this episode we explore the concept of spatial justice and establish additional terminology to better understand and analyze related phenomena. We hope that this allows you to better recognize and describe instances of spatial injustice in your environment.

03 | Energy Transition

In this episode we are looking at theories about technological innovation to better understand the currently ongoing transition of our energy system. We discuss relevant components of the new energy system, political drivers and barriers, and hypothesize about what our energy system might look like in the future. References AG Energiebilanzen e.V.

02 | History of the energy system

In this episode we are retracing the historic development of the energy systems since earliest civilizations. Our use of energy has always been interrelated with human development, innovation, and progress. By learning about how the energy system has developed alongside human societies, we want to give you some context for the upcoming transition towards decarbonized energy systems.

01 | What is infrastructure?

What is “infrastructure”? Is it limited to roads, bridges, and energy systems or does it extend to ecosystems, care work, and social institutions? In this opening episode we interrogate the concept of infrastructure from different perspectives. Moving beyond conventional definitions, we explore infrastructure as a system that is not only physical but also relational, institutional, and deeply embedded in human life. Drawing on insights from systems theory, anthropology, and political economy, we discussion the expanding scope of infrastructure to include green (natural) systems and social reproduction processes.
