EU加盟国が一次エネルギーを有効エネルギーへどれだけ効率的に変換しているか、またその効率が炭素排出にどう影響するかを欧州委員会DG Energyのデータで分析した研究。システム変換効率64.22%、エネルギー損失35.78%、炭素強度2.0894 Mt CO2/Mtoeを報告し、加盟国を効率と排出削減の達成度で順位付けする。2024年にかけてEU全体で変換効率が上昇し炭素強度が低下した傾向を示す。
English
This study assesses how efficiently EU member states convert primary energy into useful energy and how that efficiency affects carbon emissions, using European Commission DG Energy data. It reports system conversion efficiency of 64.22%, energy loss of 35.78%, and carbon intensity of 2.0894 Mt CO2/Mtoe, then ranks member states by efficiency and emission-reduction performance. The EU trend shows rising conversion efficiency and falling carbon intensity toward 2024.

📄 Abstract（原文）
Industry 5.0 challenges European industries to elevate their systems with the help of technological and digital transformations and at the same time motivates them towards the achievement of sustainable development goals (SDGs). Energy system transformations and sustainable transitions are the key concepts for decarbonizing energy sources, believed to greatly contribute to the achievement of climate neutrality. The present study assesses how efficiently the member states of the European Union (EU) convert primary energy into useful energy and how this efficiency affects carbon emissions, using energy data collected by the Directorate-General for Energy of the European Commission. We analyze the relationships between energy conversion efficiency and carbon emissions based on metrics, including system energy conversion efficiency, carbon intensity of energy use and the energy loss ratio, and report an energy conversion efficiency of 64.22%, with an energy loss of 35.78% and a carbon intensity of 2.0894 Mt CO2/Mtoe. Furthermore, by classifying the member states, we rank them by their success rate in relation to efficient energy conversion and emission reduction. Overall, the current trend in the EU shows that by 2024 the member states managed to increase their energy conversion efficiency and decrease the carbon intensity considerably, compared to previous years.
