It revealed global water withdrawals for energy production in 2010 were estimated at 583 billion cubic metres (bcm), out of which water usage – that was withdrawn but not returned to its source – was 66bcm or around 11%.
Water is critical for electricity generation as well as the extraction, transport and processing of fossil fuels and the irrigation of crops that go into biofuels. Water shortages in India and the US, among other countries, have however limited energy output in the last two years while the “heavy use of water in unconventional oil and gas production has generated considerable public concern”, the IEA said.
Its report looked at three difference scenarios – the New Policies Scenario, the Current Policies Scenario and the 450 Scenario.
Global water withdrawals for energy production reach 690bcm in 2035 in the New Policies Scenario, with growth slowing after 2020. Withdrawals in the Current Policies Scenario – which assumes no change in existing energy-related policies – continue to rise throughout the projection period, climbing to 790bcm in 2035.
