It is on the nexus water & energy. Both are linked strongly together as the following key messages suggest.
1. Water requires energy and energy requires water
Water is required to produce nearly all forms of energy. Energy is needed at all stages of water extraction, treatment and distribution.
2. Supplies are limited and demand is increasing
Demand for freshwater and energy will continue to increase significantly over the coming decades. This increase will present big challenges and strain resources in nearly all regions, especially in developing and emerging economies.
3. Saving energy is saving water. Saving water is saving energy
Choices concerning the supply, distribution, price, and use of water and energy impact one another.
4. The “bottom billion” urgently needs access to both water and sanitation services, and electricity
Worldwide, 1.3 billion people cannot access electricity, 768 million people lack access to improved water sources and 2.5 billion people have no improved sanitation. Water and energy have crucial impacts on poverty alleviation.
5. Improving water and energy efficiency is imperative as are coordinated, coherent and concerted policies
Better understanding between the two sectors of the connections and effects on each other will improve coordination in energy and water planning, leading to reducing inefficiencies. Policy-makers, planners and practitioners can take steps to overcome the barriers that exist between their respective domains. Innovative and pragmatic national policies can lead to more efficient and cost effective provision of water and energy services.
