Growing global energy use threatens water supplies, UN warns.

Guardian: “Growing demand for energy will put increasing pressure on the world’s already strained water resources, particularly in developing and emerging economies, the UN has warned.”
“There is an increasing potential for serious conflict between power generation, other water users and environmental considerations,” it says in the world water development report, published on the eve of world water day on Saturday.
Energy production accounts for close to 15% of the world’s water usage, but that figure could rise. By 2035, water use for energy is projected to jump by 20%, the report says. Water demand, meanwhile, could increase by 55% by 2050.
Much of this is due to growing populations and economies in China, India and the Middle East, says the report, which pulls together data from a range of studies. Some 90% of the global increase in demand for energy in the coming years will come from outside the Organisation for Economic Co-operation and Development (OECD), club of rich countries, it notes.
….About 90% of power generation is water-intensive, says the report, which warns that less conventional oil and gas production, including via tar sands and fracking – along with biofuels – place particularly large demands on water resources.
….Estimates suggest 768 million people are without clean drinking water, and 2.5 billion lack access to even basic sanitation. Some 1.3 billion are not connected to power grids, and close to 2.6 billion people use solid fuel, mainly biomass, to cook.”
