The role of IT in energy systems: the digital revolution as part of the problem or part of the solution; [Die Rolle von IT im Energiesystem: die digitale Revolution als Teil des Problems und Teil der Lösung]

The architectural design of our energy systems dates back to a time without information technology (IT). Over time, IT was applied where it increased efficiency and safety. About 12 years ago, the Smart Grid era began. In the meantime, we talk about digitalization. Electrical energy systems require embedded systems, Internet of Things, computation clusters and data analytics. However, IT also has another role in the energy system, namely that of a substantial consumer. Crypto currencies and data centers are on the rise. We analyze impacts on energy demand and discuss risks and chances of this development. © 2020, The Author(s).
