Clustering analysis of energy consumption data in EU regions and other countries of the war ld

This study aims to analyze energy consumption patterns across selected nations from Africa, America, Asia/Middle East, and Europe, with a focus on the types of energy sources used. Covering 46 countries, the research spans the years 2000 to 2018 and examines the distribution and changes in energy consumption by source and type. The regions studied include diverse countries such as Austria, Sweden, Czechia, and Croatia in Europe; Algeria, Egypt, and South Africa in Africa; China, India, and Saudi Arabia in Asia/Middle East; and Brazil, Canada, and the United States in the Americas, with Australia and New Zealand representing Oceania. Utilizing data from the BP Statistical Review of World Energy and the SHIFT Data Portal, along with key indicators maintained by Our World in Data, the study employs methods such as descriptive statistics, cluster analysis using k-means, and time-series clustering with dynamic time warping (DTW). The analysis highlights regional similarities and variances in energy use, providing new insights into the complex relationship between energy consumption patterns and factors such as economic growth, national policies, and geopolitical contexts. This research addresses a significant gap in the existing literature by offering a detailed comparative analysis of how different nations manage and consume energy. It contributes to the broader discourse on sustainable energy policies and economic development in the face of global energy challenges.
