Facts and figures
The Facts and Figures in this section are drawn from the upcoming edition of the World Water
Development Report on Water and Energy that will be published in March 2014 and launched on the
occasion of World Water Day celebrations in Tokyo, Japan.

Hydroelectricity
Hydroelectricity is currently the largest renewable source for power
generation in the world. Hydropower’s share in total electricity generation
is expected to remain around 16% through 2035.

Hydropower and water use
Most of the water used for hydropower generation is returned to the river
though some is consumed (reservoir evaporation) and there are important
impacts on timing and quality of streamflows.

Industrial water use
Roughly 75% of all industrial water withdrawals are used for energy
production.

Financing water
For developing countries alone $103 billion per year are required to
finance water, sanitation and wastewater treatment through 2015.

Energy for water
Energy is required for two components of water provision: pumping and
treatment (before and after use).
