Title: The Energy-Water Nexus and the Role of Civil Engineers: Interdisciplinary Systems Analysis Abstract: The energy-water nexus is a complex relationship between different energy and water resources. The energy sector depends on water for mining and refining conventional fuels, cooling thermoelectric power plants, cultivating feedstocks and processing biofuels, and hydraulic fracturing of unconventional fuels. The water sector depends on energy for collecting source water, treating and distributing drinking water, end-use water heating, collecting and treating wastewater, and reusing water. Consequently, water challenges can translate to energy challenges, and vice versa. Fortunately, civil engineers can play a valuable role in implementing technology and policy strategies to better manage energy and water. This seminar will present methods and results of interdisciplinary systems analysis applied to energy-water nexus situations, revealing some of the possible areas in which civil engineers can contribute to sustainable energy and water management.
