S-D8 Integrating Water and Energy Efficiency

Texas and California are in the midst of multi-year droughts, yet both rely heavily on electricity sources that require copious amounts of water and contribute to this prolonged drought (namely, natural gas, coal and nuclear). Using these two states as case studies, this panel will explore the inextricable link between energy and water, the need to harness data and technology to spark behavioral changes in Texans and Californians, as well as better coordination between the two sectors.

Citing specific pilot and demonstration projects, in Texas, California, and elsewhere, the panel will help audiences understand how people, businesses, and government can adopt and adapt to the new technology landscape to increase energy and water efficiency.

Dr. Edward Spang is an Assistant Professor of Food Science and Technology at the University of California, Davis. His research focuses on characterizing and optimizing the efficiency of linked water, energy, and food resource systems. He is particularly interested in applying methodologies to measure and monitor these systems and their interrelationships in high-resolution and across multiple scales. He also seeks to understand the influence of markets, innovation, and policy on the integrated food-energy-water nexus. His recent publications explore mapping energy flows through water infrastructure, enhancing the conservation signal and stability of water rates, and estimating global water consumption for energy production. Dr. Spang also serves as Associate Director of the Center for Water-Energy Efficiency at UC Davis. (esspang@ucdavis.edu)
