Water and Energy
Water and energy are closely interlinked and interdependent. Energy generation and transmission requires utilization of water resources, particularly for hydroelectric, nuclear, and thermal energy sources.
Conversely, about 8% of the global energy generation is used for pumping, treating and transporting water to various consumers.
In 2014, the UN is bringing its attention to the water-energy nexus, particularly addressing inequities, especially for the ‘bottom billion’ who live in slums and impoverished rural areas and survive without access to safe drinking water, adequate sanitation, sufficient food and energy services.
It also aims to facilitate the development of policies and crosscutting frameworks that bridge ministries and sectors, leading the way to energy security and sustainable water use in a green economy. Particular attention will be paid to identifying best practices that can make a water- and energy-efficient ‘Green Industry’ a reality.
Join us in this celebration and spread these messages:
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.
