The Water-Energy Nexus
The Water-Energy Nexus represents a critical business, security, and environmental issue, but has not yet received the attention that it merits. Energy production consumes significant amounts of water and vice versa. The evolution of both traditional and renewable energy production toward potentially more water-intensive technologies risks intensifying the demands on water resources. Newer technologies are being developed to reduce water consumption; however, they are generally expensive, can reduce efficiency, and will need time before they can be commercially available at scale. Now --as energy policies are being considered around the world-- is the window of opportunity to include water on the agenda alongside cost, carbon, and security considerations. What do businesses, the military, policy makers, and the media need to know about managing trade-offs between water and energy?
