| contents | Accurate projections of wind energy potential under climate change are critical for effective long-term energy planning. While previous studies have highlighted the value of multi-model ensembles, they often fall short in capturing the full spectrum of uncertainties and temporal dynamics relevant to wind resource reliability. This paper presents one of the most comprehensive assessments to date, leveraging a large ensemble of 21 high-resolution RCM-GCM combinations from the EURO-CORDEX initiative to evaluate future wind energy conditions across Europe under the RCP8.5 scenario. Moving beyond mean values, we incorporate a novel event-based framework to analyze persistent high- and low-wind episodes using ERA5-derived percentile thresholds -- capturing operationally critical conditions that influence turbine performance and grid stability. To ensure statistical rigor, we apply the IPCC AR6 `Approach C' for robustness assessment, distinguishing climate signals from internal variability and quantifying model agreement. Crucially, we demonstrate that projections based on limited sub-ensembles can lead to contradictory or misleading conclusions, underscoring the essential role of ensemble diversity. The combination of spatial granularity, temporal detail, and formal uncertainty quantification makes this study a significant advancement in climate-informed wind energy research and a valuable tool for resilient energy system design. |
