Saturday, March 22nd, was World Water Day. Recognized by the United Nations since 1993, World Water Day aims to raise awareness of the issues surrounding the conservation and development of water resources as well as practical policy options to address those issues. Previous years have focused on issues such as “Water Quality” and “Water and Food Security.” The 2014 day was dedicated to the “nexus” of water and energy.
It is easy to forget just how interconnected these two issues are.
Of course it takes energy to extract, treat, and distribute water; "about 8% of the global energy generation is used for pumping, treating and transporting water to various consumers." But it also takes great quantities of water to produce energy, particularly certain types such as hydroelectric, nuclear, and thermal. UN Water also estimates that a rising demand in biofuels could significantly increase the demand for water in energy production.
