The United States power sector uses immense quantities of water and is vulnerable to drought, water mismanagement, and climate change. Integrated management of energy and water systems is therefore critical, yet is hindered by disparate and delayed information. We present the Energy-Water-Emissions Dashboard (EWED) as an integrative modeling approach and exemplary web-based user interface displaying monthly generation, water withdrawal and consumption, and greenhouse gas emissions at nearly 10,000 U.S. power plants from 2003 to the most recent data available. EWED users may view aggregated results at larger spatial scales including watersheds, where they are compared to modeled water availability data. EWED also models projections out to 2050 based on a range of energy and climate scenarios, finding that water resources will continue to play a critical role in energy sector transitions. As such, EWED supports efforts to integrate decision making on immediate and long-term management challenges at energy-water-climate nexus.

美国电力部门使用大量水资源，容易受到干旱、水资源管理不善和气候变化的影响。因此，能源和水系统的综合管理至关重要，但由于信息的差异和延迟而受到阻碍。我们将能源-水-排放仪表板 (EWED) 作为一种综合建模方法和示例性基于 Web 的用户界面，显示从 2003 年到最新数据的近 10,000 家美国发电厂的每月发电量、取水量和消耗量以及温室气体排放量可用的。EWED 用户可以查看包括流域在内的更大空间尺度的汇总结果，并将其与模拟的可用水量数据进行比较。EWED 还根据一系列能源和气候情景对到 2050 年的预测进行建模，发现水资源将继续在能源部门转型中发挥关键作用。因此，EWED 支持针对能源-水-气候关系中的当前和长期管理挑战整合决策的努力。
