| Summary: | The article examines the innovative trends in the renewable power generation, taking into account the impact of crises, as well as the impact of renewable energy on air pollution in the world (environmental change). Hierarchical agglomerative and iterative methods of cluster analysis, as well as econometric models were used to test the hypotheses. Carbon dioxide emissions and renewable power generation for 78 countries during 2000-2020 are taken into account as the database of the study. The results showed that there are groups of countries with sharp, high, moderate and low growth rates of renewable power generation. In addition, the results of econometric analysis indicate that the growth of renewable power generation does not always cause a decrease in carbon dioxide emissions. For a number of countries (Australia, Canada, Mexico, Poland) such connection is not essential at all. The results of the study can be useful in shaping and adapting environmental strategies around the world.
