Abstract
Purpose: The article aimed to understand the structure of the energy mix in EU countries, particularly in comparison with Poland, from 1990-2022. Design/methodology/approach: The research was conducted on data from 27 EU countries between 1990 and 2022 using statistical methods with particular emphasis on analysis of the dynamics of phenomena and clustering. Findings: Studies have confirmed a substantial increase in the share of renewable energy sources (RES) in the energy mix of the EU countries. A considerable increase was recorded in wind and solar energies. However, solid fuels still are in use in EU countries, particularly in countries whose economies are based on coal, including Poland. Originality/value: The article’s value is to view the development energy mix in Poland and the EU from a multidimensional analysis conducted in two separate time units. It allowed conclusions about the development of RES in Poland and the EU to be drawn.
