Energy Down the Drain: The Hidden Costs of California’s Water Supply (2004)

  back to resources page

This research quantitatively evaluated the connections between energy and water in three case studies, using San Diego County’s search for future water supply options to high-light energy use in urban water systems and the Westlands Water District and the Columbia River Basin illustrate energy use in agricultural settings. Key findings include: water saving reduces energy use and bills, diverting water above dams costs power and money, water recycling is a highly energy efficient water source and Retiring agricultural land may increase energy use if the water is transferred to other agricultural or urban uses but can decrease energy use if it is diverted to the environment
