Kümeleme analizi k-ortalama yöntemi ile seçili ülkelerin enerji tüketimlerine göre incelenmesi

In this study, countries (Australia, Austria, Azerbaijan, Belgium, Brazil, Bulgaria, Canada, China, Chile, Colombia, Denmark, Egypt, Finland, France, Germany, Greece, Hungary, India, Indonesia, Iran, Iraq, Italy, Japan, Kazakhstan, Luxembourg, Mexico, New Zealand, the Netherlands, Norway, Pakistan, Poland, Portugal, Russia, Spain, Sweden, Switzerland, Thailand, Turkey, the United Kingdom, the United States, and Uzbekistan) were clustered based on their energy consumption for the years 2000 and 2021. In line with the objectives of the study, data on nuclear energy, coal consumption, oil consumption, natural gas consumption, hydropower consumption, and renewable energy consumption were used to represent energy consumption. The clustering analysis revealed differences between countries in the clusters formed between 2000 and 2021. The transition of countries such as Iran, the Netherlands, Mexico, and Luxembourg from Cluster 1 in 2000 to Cluster 2 in 2021 illustrates the complexity of changes in energy consumption patterns. Factors underlying these changes include changes in energy policies, economic conditions, international relations, and technological advances. Similarly, the transition of countries such as Canada, Germany, Italy, Spain, and the United Kingdom from Cluster 2 in 2000 to Cluster 1 in 2021 can be attributed to various factors such as changes in energy policies, economic growth or stagnation, technological progress, shifts in international trade relations, and environmental considerations.
