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

It also aims to facilitate the development of policies and

economy. Particular attention will be paid to identifying best practices
that can make a water- and energy-efficient 'Green Industry' a
