ANALYSIS OF ENERGY SUSTAINABILITY PERFORMANCES OF G7 COUNTRIES: AN APPLICATION WITH OWA OPERATOR AND CODAS METHODS

Abstract

It is important to analyze the energy sustainability performances of the G7 countries, especially since G7 countries have an important place in carbon emissions in the world and the development of energy sustainability activities of these countries can affect energy policies of other countries and the global economy. In this context, the energy sustainability performances of the said countries were measured by OWA operator and CODAS methods, over the values of the World Energy Trilemma Index components of G7 countries for the latest and current 2021. In research, energy sustainable performances of the countries are listed as England, France, Canada, Germany, USA, Italy and Japan according to OWA operator method, and as Canada, France, England, Germany, USA, Italy and Japan according to CODAS method. In study, the average energy sustainable performance values of countries were also measured according to both methods and It was determined that the countries that are below the average energy sustainability performance value are Italy and Japan. Therefore, according to this result, it was evaluated that Italy and Japan should increase their energy sustainability performance in order to be in accordance with other G7 countries in terms of energy sustainability and to contribute more to global energy sustainability.
