Abstract

Complexity science facilitates the understanding of the operation andbehaviour of complex systems, such as energy systems. As an initial step, it is necessary to select suitable modelling approaches and methods for analysing a given energy system. In this process, systems thinking (as opposed to thinking in isolated parts) comes to the fore, particularly when making decisions that affect the entire energy sector, but also in wider engineering practice. Models of energy systems and structures enable systematic and analytical comparison between different energy transition scenarios. Therefore, special emphasis is placed on understanding multi-objective design theoryand multi-objective modelling. This approach promotes the development of sustainable and resilient energy system architectures.When analysing the futureprospectsofenergy systems, both driving forces and barriers emerge. Consequently, an integrated assessment of global effects s is also a key part of the analysis. As a novel approach, the paper draws a parallel between musical composition and engineering modelling (Model of Energy Systems and Structures to Analyse Global Effects = MESSAGE), using Ravel’s Boléroas an illustrative example. The incrementally developingstructure of Ravel’s Boléro serves as an analogy for the staged evolutionof energy systems.Systematic comparison demonstrates the need to enable objective evaluation of alternative solutions, thereby supporting the selection of optimal design options and models. Overall, the MESSAGE framework serves to assess energy system development and global impacts in an integrated way. In the energy sector, systems thinking and modelling/simulation are essential for coordinating tasks, solving problems effectively, and managing processes in an oriented way. The complexity of tasks, problems, and challenges emphasises the importance of dialogue in energy decision-making.
