The aim of the paper is to assess the potential of renewable energy sources (RES) in Poland. We analyse the installed capacity and the amount of electricity generated from renewable energy sources, as confirmed by issued certificates of origin. Additionally, the study examines the structure and dynamics of the capacity of renewable energy installations at the voivodeship level, covering the period from 2017 to 2023. The data comes the Energy Regulatory Office. The results reveal significant growth in renewable energy capacity over the analysed period, with wind and solar energy showing the most substantial increases. Wind power remains the largest contributor to Poland’s renewable energy production, while solar power experienced rapid expansion. The analysis also highlights regional disparities. Podlaskie, West Pomeranian, and Kuyavian-Pomeranian voivodeships are leading in terms of installed capacity, particularly in wind energy, which remains the largest contributor to Poland’s renewable energy production. Conversely, regions such as Lubusz, Opole, and Holy Cross show slower progress and lag behind in renewable energy development.
