15% of the world’s total water withdrawals are used for energy production
Whereas energy is required mainly for the provision of water services, water resources are required in the production of energy. In 2010, 15% of the world’s total water withdrawals – about 583 billion m3, or roughly 75% of all industrial water withdrawals - were used for energy production. Water demand for energy will certainly increase as energy demand is expected to increase by more than one third in the period 2010–2035. Approximately 90% of global power generation is water intensive: water is used directly for hydropower generation as well as for all forms of thermal power generation schemes.
