Water for energy: Characterizing co-evolving energy and water systems under twin climate and energy system nonstationarities
Payne Institute Faculty Fellow Adrienne Marshall and Emily Grubert write about how as water-for-energy quantification efforts progress, research should emphasize decision support for energy system design, incorporating crucial hydrologic dynamics. Beyond the location of water use, relative scarcity, and potential competing uses, these include sub-daily to interannual temporal dynamics, the impacts of climate change on these dimensions, potential feedbacks between energy and water systems, and the impacts of hydrologic variability or change on policy-based incentive structures. This article reviews prior US-focused efforts to quantify water use for energy, highlights why these nonstationarities are analytically relevant with a brief policy case study, and highlights research needs for decision support under twin nonstationarities.
