Modelling the Energy Transition in Cities

The history of cities is a history of energy transi tions. In the medieval city heating and cooking occurred with wood and peat. The growth of the industrial city in the 19th century was built on coal and electricity. The sprawling metropolis of the 20th century was made possible by oil and gas. How will the city of the 21st century look after th e next energy transition from fossil to renewable energy? This paper reports on the extension of an urban land-use transport interaction model to a mod el of the energy transition in the Ruhr Area, a five-million agglomeration in Germany. The paper presents the planned model extensions and how they are to be integrated into the model and shows first preliminary results.
