EUのエネルギー価格高騰と供給ギャップに対応するため、GAINSモデルと統合評価モデルを組み合わせ、短期的・長期的なエネルギー移行戦略を評価。長期的な再生可能エネルギーへの移行は供給ギャップを解消し、GDP比約3%の純便益をもたらす。高エネルギー価格下では目標前倒しの便益がコストを上回るが、急速な再生可能エネルギー拡大によるLCOE変動を考慮しないと過大評価につながる。
English
This study introduces a framework integrating the GAINS model with a system dynamic integrated assessment model to evaluate EU energy strategies under high prices. It finds that long-term renewable energy transitions close the energy gap and yield net benefits equivalent to ~3% of projected 2050 GDP. Accelerating targets by 5-20 years can be cost-effective under current high prices, but dynamic LCOE trends must be considered to avoid overestimating benefits.

日本のGX文脈において
EUのエネルギー危機と脱炭素化の両立を分析した本研究は、日本のエネルギー政策（洋上風力や水素導入など）にも示唆を与える。特に、高エネルギー価格下での再生可能エネルギー投資の経済性評価は、日本のGX推進における政策設計の参考となる。
In the global GX context
This paper provides rigorous quantitative evidence on the economic and environmental benefits of accelerated renewable energy deployment under high energy prices. It is highly relevant for global GX discussions, especially in contexts where energy security and transition costs are debated. The findings support strong policy intervention to manage energy prices and incentivize green investments.
👥 読者別の含意
🔬研究者:The integrated modeling approach (GAINS + WILIAM) and the dynamic LCOE adjustment offer methodological advances for energy transition analysis.
🏢実務担当者:Corporate sustainability teams can use the cost-benefit analysis to justify renewable energy investments and long-term decarbonization strategies.
🏛政策担当者:Policy makers should consider the net benefits of accelerating renewable targets and actively adjust energy prices to facilitate a green transition.
📄 Abstract（原文）
Geopolitical tensions and the disruption of major energy imports have sharply elevated energy prices across the European Union (EU), creating a persistent energy supply gap and posing long-term challenges for energy security. Here, we introduce a comprehensive framework integrating the advanced Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model with a system dynamic WILIAM (“Within limits”) Integrated Assessment Model to systematically evaluate strategies for closing this energy gap. We find that measures to close the energy gap in the short term exacerbate either economic or public health burdens, highlighting the need for more sustainable solutions in the long term. Our further analysis shows that long-term strategies focused on renewable energy transitions not only close the energy gap but also bring net benefits equivalent to ~3% of projected GDP for 2050. Moreover, we find that rising energy prices substantially influence the cost-effectiveness of accelerated energy transitions. Under current high energy price levels, the benefits from achieving energy targets set for 2050 by 5 to 20 y in advance could outweigh the additional costs. The consideration of dynamic trends in the levelized cost of electricity (LCOE), particularly under rapid renewables expansion, is critical for avoiding overly optimistic estimations of green transition benefits. Our findings suggest that a timely transition to renewable energy benefits the EU in the face of the energy crisis, and policies proactively adjusting energy prices could facilitate a greener, more sustainable future.
