“…These are reasons why there is a paradigm shift towards open methods in energy modelling projects ( Morrison, 2018 ), as also reflected in the contributions of this special collection. It presents new open datasets ( Sterl et al , 2022 ) and new methods for citizen-driven data collection ( del Cañizo et al , 2021 ) as well as a better processing of open data sets ( Fleischer, 2022 ) to increase the use of open data in modelling. Additionally, the collection presents a new tool for the analysis and visualisation of results ( Huppmann et al , 2022 ) to streamline the postprocessing pipeline.…”
