The Water-Energy Nexus
Water needs energy to move and treat; energy needs water to generate power.
Pumping, treating, and heating water consume large amounts of energy. Power plants need cooling water. Hydropower uses falling water directly.

Saving water often saves energy, and efficient energy systems reduce water stress.
Why the Nexus Matters
Planning water and energy together avoids solving one problem by worsening the other — especially under climate stress.
Understanding the water-energy nexus is essential for sustainable planning.
