Book Description
This analysis provides a description of the first U.S. national electricity capacity expansion model to incorporate water resource availability and costs as a constraint for the future development of the electricity sector. The Regional Energy Deployment System (ReEDS) model was modified to incorporate water resource availability constraints and costs in each of its 134 Balancing Area (BA) regions along with differences in costs and efficiencies of cooling systems. Scenarios analyzed include a business-as-usual scenario without water constraints as well as four scenarios that include water constraints and allow different cooling systems and types of water resources to be utilized. This analysis provides insight into where water resource constraints could affect the choice, configuration, or location of new electricity technologies.

Book Description
Climate change has the potential to exacerbate water availability concerns for thermal power plant cooling, which is responsible for 41% of U.S. water withdrawals. This analysis describes an initial link between climate, water, and electricity systems using the National Renewable Energy Laboratory (NREL) Regional Energy Deployment System (ReEDS) electricity system capacity expansion model. Average surface water projections from Coupled Model Intercomparison Project 3 (CMIP3) data are applied to surface water rights available to new generating capacity in ReEDS, and electric sector growth is compared with and without climate-influenced water rights. The mean climate projection has only a small impact on national or regional capacity growth and water use because most regions have sufficient unappropriated or previously retired water rights to offset climate impacts. Climate impacts are notable in southwestern states that purchase fewer water rights and obtain a greater share from wastewater and other higher-cost water resources. The electric sector climate impacts demonstrated herein establish a methodology to be later exercised with more extreme climate scenarios and a more rigorous representation of legal and physical water availability.

Book Description
We use an innovative methodology to model the socioeconomic linkages between water, energy, and food in the East Nile Basin. Based upon a theoretical nexus framework, the methodology is expanded into a quantifiable modeling suite that under-lies the analysis of each of three country case studies. The advantages are that, despite resource shortages being a challenge, the modeling suite aids in devising policies and strategies that formulate these sectoral interdependencies and provide the evidence-based research results necessary for their design in a way that exploits synergies existing across sectors, countries, and regions (Al-Zubari n.d.). This paper lays out the methodology and gives an example of an application and scenarios by focusing on three countries in the East Nile Basin. This methodology paper will be followed by three individual country case studies that highlight the water, energy, and food nexus for each.

Book Description
Increasing competition for water resources in the United States could create future challenges for allocating and using thermal cooling water in the U.S. electric power sector. While thermal power plant retirements and the growth of wind and solar technologies can reduce national aggregate power sector cooling water use, local water constraints and growing demand for agricultural or municipal supply could create greater needs for higher-cost alternative water supplies such as groundwater or recycled wastewater. For some regions, these incentives could change future electricity planning and operational decisions. These relationships and impacts are studied here using the National Renewable Energy Laboratory (NREL) Regional Energy Deployment System (ReEDS), a national electric sector planning model that has recently been upgraded to include a highly detailed representation of thermal cooling water demand and supply. Thermal power technologies are differentiated by both cooling technology and water source type to track and constrain thermal cooling water use in a way that incorporates both physical and legal water considerations in the United States. This capability is exercised under a range of electricity sector futures with alternative technology costs, fuel prices, and water constraints to illustrate ways that U.S. electric sector water use could evolve under uncertain future electric sector drivers. In exploring changes to regional generation and transmission planning and operation, water requirements, and cost, we highlight the environmental and economic impacts of future power sector water decisions.

Book Description
This book examines water resource management in China’s electric power sector and the implications for energy provision in the face of an emerging national water crisis and global climate change. Over 75% of China’s current electricity comes from coal. Coal-fired power plants are reliant on water, with plants using significant volumes of water every year, yet water resources are unevenly distributed. In the face of serious environmental concerns and increasing electricity demand, this book examines the environmental impacts that coal power plants have on water resources and the impact water availability has on the electricity sector in a country with a significant number of water-scarce provinces and a large number of power plants located on inland waterways. It discusses the water impacts and constraints for transforming the electric power sector away from coal to renewable energy sources, such as hydropower and concentrated solar power. The book adopts a mix-method approach, combining a plant-level quantitative analysis on water impacts and dependencies in China’s electricity sector and a qualitative analysis of relevant institutions in both sectors. By reviewing policy and institution cases in China’s water and electricity sectors, the book provides important recommendations calling for coordinated institutions to shift away from the current paradigm where water and electricity are governed independently. Enriching the water-energy nexus literature, this book will be of great interest to students and scholars working on water resource management, energy industries and Chinese environmental policy, as well as policymakers and practitioners in those fields.

Book Description
The nation's energy choices embody many tradeoffs. Water use is one of those tradeoffs. The energy choices before Congress represent vastly different demands on domestic freshwater. The energy sector's water consumption is projected to rise 50% from 2005 to 2030. This rising water demand derives from both an increase in the amount of energy demanded and shifts to more water-intense energy sources and technologies. This report discusses this issue as well as related issues that may arise for the 112th Congress.
