Abstract: The aim of this paper is to determine the dependence between the installed capacity of wind power plants and annual CO2 production, as well as between coal energy use and CO2 production. Pearson and Spearman correlation methods are used for the analysis based on the normality of data, which was tested using the Shapiro-Wilk test of normality. The results show a negative correlation between the capacity of wind power plants and CO2 production in Belarus, Russia, and Norway, while in Spain and Germany, the correlation is positive. Furthermore, a positive correlation between coal energy use and CO2 production is found in the Czech Republic, Poland, Austria, Portugal, Italy, Greece, and Denmark, which aligns with expectations. Conversely, a negative correlation is found in Ireland and Lithuania, which may indicate more efficient energy use. Limitations are identified in the form of different correlation tests, which may partially distort the results. This work contributes to research in the field of energy and can be useful for the development of political and energy plans.
