Eurostatの2013〜2023年データを用い、ダニューブ地域各国の最終エネルギー消費に占める再エネ比率の推移を比較分析した実証研究。水力が安定供給と低炭素で優位な一方、水文条件や生態系への影響が制約となる。太陽光・風力・バイオマスへの投資が拡大し、国ごとに異なる導入パターンが確認された。気候変動による河川流量変化が水力発電に及ぼす影響も論じ、地域のグリーンエネルギー協力の可能性を示す。
English
Using Eurostat data for 2013–2023, this study empirically compares the evolution of renewable energy shares in gross final consumption across Danube region countries. Hydropower offers stable, low-carbon output but is constrained by hydrology and ecosystem impacts, while solar, wind, and biomass investment is rising with distinct national patterns. The authors note climate change effects on river flow and hydropower, and highlight regional cooperation and EU policy as enablers of the green transition.

日本のGX文脈において
日本企業・政策担当者にとっては、EUの再エネ比率目標と地域横断協力の実装例として参考になる。特に水力依存のリスクと気候変動影響の評価は、国内の再エネ電源構成や長期エネルギー政策を考える上で示唆に富む。SSBJ開示の文脈では直接の接点は薄い。
In the global GX context
This paper adds regional empirical evidence to the global energy-transition literature, illustrating how EU renewable targets translate unevenly across member states and how climate-driven hydrological change creates physical risk for hydropower assets. It is relevant to transition-finance and climate-risk discussions but does not engage TCFD/ISSB disclosure frameworks directly.
👥 読者別の含意
🔬研究者:Provides a comparative, decade-long Eurostat-based baseline of renewable penetration patterns across Danube countries useful for regional energy-transition studies.

📄 Abstract（原文）
The Danube holds a strategic position and is a key region for economic cooperation, transportation, and energy security. In the context of the global energy transition and the European Union’s climate neutrality objectives, sustainable energy is becoming central to the future of the Danube region. This paper presents an empirical analysis of renewable energy development in the Danube region. The study is based on Eurostat data covering the period 2013–2023 and examines the evolution of the share of energy from renewable sources in gross final energy consumption across the analyzed countries. Hydropower offers important advantages, including relatively stable energy production and low carbon emissions, but its dependence on hydrological conditions and impacts on aquatic ecosystems are major limitations. Beyond hydropower, solar and wind energy are gaining increasing importance in the Danube region. Over the last decade, investment in these renewable sources has increased significantly, reflecting different patterns of renewable energy development across the countries analyzed. Biomass is also an important component of sustainable energy in the Danube region, especially in rural areas. The use of agricultural residues, forestry waste, and dedicated biomass contributes to the production of heat and electricity while supporting the local economy. However, the development of sustainable energy in the Danube region faces many challenges. Climate change is having a direct impact on the hydrological regime of the Danube, affecting the flow of the river and, consequently, hydropower production. The empirical results indicate a general upward trend in the share of energy from renewable sources during the 2013–2023 period, although the extent and pace of change vary from one country to another among those analyzed. Based on descriptive statistics and comparative analysis, the conclusions highlight different national patterns regarding the integration of renewable energy sources. This study outlines the region’s potential to support the European energy transition and regional green energy cooperation. At the same time, the paper aims to highlight existing opportunities and good practices at the regional and European levels, emphasizing cross-border cooperation, EU policies, and the role of technological innovation.
