本レビューは、気候変動と極端気象が太陽光・風力・水力の発電性能と信頼性に与える影響を全球的に統合した。再エネ干ばつの指標（標準化再エネ生産指数、容量係数閾値など）を整理し、欧州の冬季風力干ばつ、中国の秋季風力・冬季太陽光不足、北アフリカの脆弱性、世界的な水力低下を示す。ハイブリッド化・蓄電・系統連系がレジリエンスを高め、高排出シナリオでリスクが増大すると結論づける。
English
This critical review synthesizes how climate variability and extreme events drive renewable-energy droughts across solar, wind, and hydropower systems. It compiles indicators (standardized renewable energy production index, capacity-factor thresholds) and regional evidence: European winter wind droughts, Chinese autumn wind and winter solar shortages, North African vulnerability, and global hydropower decline. Hybrid systems, storage, and grid interconnection improve resilience, with risks intensifying under high-emission scenarios.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は再エネ比率拡大と系統制約が課題で、風力・太陽光の干ばつリスク評価は電源計画やSSBJ/TCFDの物理リスク開示に直結する。蓄電・系統連系・ハイブリッド化の知見は国内のGX電源投資判断に有用。
In the global GX context
For global disclosure scholarship, this review operationalizes physical climate risk for renewable assets, feeding TCFD/ISSB physical-risk assessment and transition planning. It supports scenario-based resilience metrics that regulators and investors increasingly expect in CSRD/ISSB-aligned reporting.

📄 Abstract（原文）
Extreme weather events and climate change increasingly affect the performance and reliability of renewable energy systems, posing significant challenges to the global clean energy transition. Despite the growing body of research on climate impacts across individual renewable-energy technologies, current knowledge remains fragmented across regions, technologies, and assessment methodologies, highlighting the need for a comprehensive synthesis of renewable-energy droughts and their future evolution under climate change. This critical review examines how climate variability and extreme events influence solar, wind, and hydropower systems, with particular emphasis on renewable-energy droughts and the indicators used to assess them, including the standardized renewable energy production index and capacity factor-based thresholds (e.g., 10% and 5%). Regionally, Europe experiences frequent winter wind droughts, with extreme events reducing energy production by more than 50% in southern regions, while solar droughts may affect up to 24% of days annually in northern Europe. In China, autumn wind droughts can persist for up to 15 days, and solar shortages may affect up to 63% of winter periods, increasing risks to grid stability. North Africa also exhibits pronounced wind and solar drought vulnerability, whereas hydropower systems worldwide are increasingly affected by hydrological droughts and altered river-flow regimes. Hybrid renewable-energy systems, energy storage, and stronger grid interconnections can substantially improve resilience to renewable-energy droughts. The review further shows that renewable-energy drought risks generally intensify under higher-emission climate scenarios, underscoring the need for standardized assessment frameworks, integrated climate-resilient planning, and greater consideration of socio-economic factors to support adaptation and future energy-system resilience.
