本研究は、CMIP6気候モデルを用いて、1.5°C、2.0°C、3.0°Cの温暖化レベルで世界の複合再生可能エネルギー干ばつ（風力と太陽光の同時低出力）を評価した。温暖化が進行するにつれて干ばつの強度、継続時間、頻度が増加し、3.0°Cでは世界の陸地の半分以上で統計的に有意な変化が見られる。機械学習分析により、太陽放射が干ばつ激化の主な要因であることが示された。

This study evaluates compound renewable energy droughts (simultaneous low wind and solar output) under 1.5°C, 2.0°C, and 3.0°C global warming levels using CMIP6 models. Drought intensity, duration, and frequency increase with warming, with statistically significant changes over half of global land area at 3.0°C. Machine learning identifies solar radiation as the dominant driver.

📄 Abstract（原文）
<title>Abstract</title> <p>The transition from fossil fuels to renewable energy is essential for mitigating human-induced climate change and achieving climate neutrality, requiring reliable and resilient renewable energy systems. However, global warming is expected to increase the instability of renewable energy resources, particularly during periods of simultaneous low wind and solar power generation, known as renewable energy droughts (REDs). Nevertheless, a consistent assessment of REDs that explicitly accounts for the compound dependence and joint variability of wind and solar resources remains lacking. Here, we investigate REDs globally under 1.5°, 2.0° and 3.0°C global warming levels (GWLs) using CMIP6 multi-model simulations, explicitly capturing their compound nature and the joint dependence between wind and solar resources. The impacts of global warming are evaluated through changes in RED intensity, duration and frequency across GWLs. Results show that REDs intensify progressively with warming, with statistically significant changes affecting more than half of global land area for all three characteristics at 3.0°C GWL. Machine learning analysis identifies solar radiation as the dominant driver of RED intensification, with influence strengthening under higher GWLs. These findings highlight the need to integrate compound risk assessments into renewable energy planning to ensure system reliability in a warming world.</p>
