ABSTRACT
Clean energy transition is the key for sustainable energy. In spite of the positive tendencies, the Covid-19 has also raised many issues and highlighted the importance of the topic. The Sustainable Development Goal 7 and 13 may serve as a basis to achieve affordable and clean energy and to combat global climate change. Meeting these objectives needs well-designed energy and environmental policy with a strong holistic approach. This study aims to build a comprehensive indicator set for measuring the sustainable energy performance of the European Union Member States. To determine the indicator set we follow rigorous steps, the methodology of which is described in detail. Finally, we present the list of eight selected indicators, from which a composite indicator can be built. Additionally, the overall structure of the dataset is analyzed through correlation analysis, stationarity and normality tests. Standardization is carried out to make the variables comparable with different units. Respecting the main dimensions of the theory of sustainable development, we also determine the weighting factors and we put them up for discussion.
