The report examines the 'water-energy nexus' in the western United States, specifically the eleven states of the Western Electric Coordinating Council (WECC). It models eight scenarios from 2008 to 2100, varying by carbon emission goals, water conservation mandates, and energy efficiency levels. The primary finding is that while power plants require water, their total consumption is small compared to agricultural and urban use, making the water-energy nexus a secondary concern in the region's broader water crisis. The analysis suggests that carbon pricing (around $70 per ton) is a more likely driver for shifting energy strategies than water pricing, as water prices would need to exceed $4,000 to $7,000 per acre-foot to make water-conserving energy scenarios the least-cost option.
