Energy Down the Drain: The Hidden Costs of California’s Water Supply analyzes the connections between power and water resources in California. The report presents several key findings: 1) water conservation lowers energy use and energy bills, 2) water recycling is a highly energy efficient water source, 3) retiring agricultural land may increase energy use if the water is transferred to other agricultural or urban uses, 4) Retiring agricultural land can save energy if the water is dedicated to the environment, and 5) diverting water above dams costs an enormous amount of power and money. Based on these findings it is recommended that decision makers better integrate energy into water policy decision-making, as well as give water conservation higher priority.
