Environmental pollution, increased energy consumption, and growing demand for the energy sector have been widely discussed. Due to policymakers and different organizations impacting a lot of new regulations, tools have been implemented to use clean energy that has zero impact on the environment. The International Energy Agency (IEA) supports energy efficiency and evaluation by developing tracking indicators and analyzing energy consumption data. The paper identifies critical indicators for efficient green energy production and ranks the IEA member countries using the CRITIC-TOPSIS method. Results showed that CO2 emissions and monitoring energy consumption are the most significant indicators while assessing the countries' performance regarding green energy production. The results indicated Sweden as the best-performing country regarding green energy production and reaching energy efficiency between 1990 and 2020. While Turkey and the USA ranked last, resulting in significantly increased CO2 emissions within the time range that need more efforts and policy implications to reach similar energy efficiency levels as other IEA countries., (© 2023.
