An Analysis of the Energy Intensity of Water in California: Providing a Basis for Quantification of Energy Savings from Water System Improvements analyzes water-related energy use in California. The report examines energy inputs to water systems for: 1) primary water extraction, conveyance, and storage, 2) treatment and distribution within service areas, 3) on-site water pumping, treatment, and thermal inputs, and 4) wastewater collection, treatment, and discharge. The report concludes that “with better information regarding the energy implications of water use, public policy and combined investment and management strategies between energy, water, and wastewater agencies and utilities can be improved.” The benefits cited for these energy savings include avoided capital and operating costs, reduced burden on rate-payers, improved distribution of capital, and environmental benefits.
