Water resources are required for cooling of thermoelectric power plants and in the production of hydroelectricity. Scarcity of water resources impacts the ability to generate electricity in grids across the globe. There is extensive literature and research on the electricity-water nexus, spanning hydrology, policy, and energy sectors. Existing research often focuses on quantifying a static relationship and rarely accounts for expectations of annual, seasonal, and subseasonal water variability in nexus research. This omission leaves an important, unanswered question in the field: how can the water footprinting framework be operationalized in the electricity-water nexus with hydroclimatic forecasts? Building off the work by Chowdhury et al. (https://doi.org/10.1029/2020EF001814), we comment on the opportunities for climate-informed, seasonal, or subannual assessments of the electricity-water nexus to facilitate decision-making.

发电中水足迹稳健性的机会

热电厂的冷却和水力发电都需要水资源。水资源的稀缺影响了全球电网的发电能力。有大量关于水电关系的文献和研究，涵盖水文、政策和能源部门。现有研究通常侧重于对静态关系进行量化，而很少考虑在关联研究中对年度、季节性和次季节水变率的预期。这一遗漏在该领域留下了一个重要的、未解决的问题：水足迹框架如何在具有水文气候预测的水电关系中运作？建立在 Chowdhury 等人的工作基础上。(https://doi.org/10.1029/2020EF001814)，我们评论了气候信息、季节性、
