The Water-Energy Nexus Issue

The Magic Nexus team

There is an increasing demand for energy to alleviate water scarcity pressures, and, vice-versa, a growing water footprint required to produce many energy forms – including new energy technologies. The governance of water and energy then is crucial if we are to safely manage these finite resources into the future.

In our first article, Zora Kovacic explores the origins of the term ‘nexus’ from its original use spearheaded by the food and beverage industry as part of the ‘green growth’ agenda, to become attached to applications as diverse as water modelling to multidisciplinary social-ecological systems analysis initiatives today. She uses the context of these varied applications to question whether the ‘nexus’ concept will help or hinder future water governance efforts.

Broaching the topic of hidden water flows, Maddalena Ripa and Violeta Cabello crunch the numbers to investigate the characteristics and size of an often invisible, yet important water flow – non-consumptive use in the energy sector.  These authors highlight the shortcomings and challenges in quantifying water flows in the energy sector today, and break down the sectors that are not – and should be - properly accounted for. The article then explains how we can improve water governance using better-defined and more comprehensive accounting methods.

Finally, Juan de La Fuente and Baltasar Peñate explore the topic of desalination as a water-energy nexus technology in the Canary Islands, Spain. These authors explain how this controversial technology, known for its large energy footprint, is a viable technology in cases where renewable energy sources are readily available. They show how the Canary Islands archipelago has alleviated its water scarcity problem using desalination technologies, thanks to solar and wind resources available in the area together with effective management to balance costs, energy availability and environmental effects.
