Logo unveiled: World Water Day 2014 - Water and Energy

04.09.2013 -

Water and Energy will be the theme of next year's World Water Day. 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. Recent interest in biofuels also creates an incremental demand on water resources; the latest World Water Development Report (2012) predicts that even a nominal increase in biofuel demand (say 5% of road transport by 2030, as predicted by International Energy Agency) could push up the water demand by as much as 20% of the water used for agriculture worldwide. Additionally, biofuel production is linked to increases in water pollution through increased used of fertilizers and agricultural chemicals. Conversely, about 8% of the global energy generation is used for pumping, treating and transporting water to various consumers. Co-production of water and energy, as is the case for geothermal energy generation, offers interesting opportunities to energy- and water-scarce countries.

The UN system – working closely with its Member States and other relevant stakeholders – is collectively 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 is being paid to identifying best practices that can make a water- and energy-efficient ‘Green Industry’ a reality; several methodologies are at play in which industrial productivity can be increased while reducing the water footprint.
