Analysis of the Potential, Use and Support for the Renewable Energy Sources in Polish Voivodeships for the Construction of Sustainable Energy Development Index

Achieving sustainable energy development will require strategic planning and monitoring the effects of selected strategies. The development of a comprehensive system of indicators and a sustainable energy index could therefore be useful to assess both the current state and the progress made towards achieving sustainable energy. The article concerns sustainable energy development at the regional level and focuses on the most important element of sustainable energy development, which are renewable energy sources (RES). Indicators describing the potential of individual RES in regions, the actual use of individual RES and the institutional dimension in the field of supporting the use of RES were taken into account. The aim of the article is a comparative analysis of the level of sustainable energy development of Polish regions in relation to the potential, use and institutional support of renewable energy sources. Taxonomic methods were used: SAW and TOPSIS. The purpose of the research in the methodological layer is to compare the results obtained with the use of SAW and TOPSIS methods and to verify the goodness of fit of both methods. Clustering was also carried out to identify similar regions in the implementation of the concept of sustainable energy development.
