Ariel Miara

Energy, Water and Environment Research Analyst


Ariel Miara is a leading energy, water, and environment research analyst in the Resources and Sustainability Group within NREL’s Strategic Energy Analysis Center.

As an energy-water nexus expert, Ariel leads research on a range of topics related to the interactions between energy systems, water resources, the environment, and policy. His modeling and analysis work includes integrating water resources and energy models to evaluate weather and climate impacts on electricity generation infrastructure.

As part of his cutting-edge energy-water nexus work, Ariel researches energy requirements for water infrastructure and innovative synergies between energy and water systems to maximize productivity and efficiency, under current and future conditions. His Thermoelectric Power and Thermal Pollution Model (TP2M) simulates power plant operations and water use, impacts on water resources and riverine ecosystems, and performance under environmental regulation and climate change.

Ariel holds a dual appointment with the City University of New York’s Advanced Science Research Center, where he is a senior research associate. Ariel completed his PhD in Civil Engineering, with a focus on water resources and environmental engineering, at The City College of New York.
