Growing energy demand adds stress to water supply

Singapore (AFP) Aug 24, 2011

A Google search for "world water shortage" will produce more than four million results in 0.17 seconds. It will also use a tenth of a teaspoon of water, experts say.

Given water's role in power generation, the impact of about 300 million Google searches a day is around 150,000 litres (40,000 gallons) daily -- in a world where water supplies are increasingly a major concern.

"These two things -- water and energy -- come together and that's a big thing for the world to understand," says Len Rodman, a US-based water and energy expert.

"If you squander water, if you indiscriminately use power, then in the long run that will have implications for the world," the chief executive of Black & Veatch, a major global water and energy company told AFP in an interview.

Water is used not only to generate power through dams and steam but also as a coolant for nuclear, coal and gas-fired power plants, which are competing with agriculture, industry and urban consumption for water supplies.

The Asian Development Bank has forecast the region's energy demand to double by 2030 to 6,325 million tonnes of oil equivalent, or about 74 billion kilowatt-hours of electricity.

Water will play an increasing role as a power source for Asia but supplies are already under threat, said the ADB.

China and India, the world's most populous nations, are expected to have a combined shortfall of one trillion cubic metres (35 trillion cubic feet) of water within 20 years.

Bangladesh, Cambodia, Nepal, Pakistan, the Philippines and Vietnam are already under "water stress" conditions, meaning they are experiencing periodic or limited water shortages.

During an international water conference in Singapore in July attended by Rodman, industry players and government officials called for better integration of water and energy policies to help find solutions to looming shortages.

"There is a growing realisation that we can no longer think about energy and water separately," Peter Gleick, president of the Pacific Institute in California, said at the conference.

A recent survey of more than 700 US utilities firms by Black & Veatch showed that for the first time, water supply was the top environmental concern among the respondents.

Asia is likely to face the same problems, Rodman said.

"It will truly be exacerbated in this region because of the urban densities that are there. You've got tremendous numbers of highly concentrated urban areas," he said.

The needs of the region's agricultural sector can also affect power supplies.

In 2008, 2.2 billion cubic metres of water were diverted from three major hydroelectric plants in Vietnam for agriculture, leading to a shortfall of 430 million kilowatt-hours of electricity, Black & Veatch said.

Research is continually being carried out on water treatment technologies that require less energy as well as power-generation facilities that would need less water, experts said.

Advanced technologies to treat polluted water as well as recycle water from toilets, kitchen sinks and sewers for use in homes and industries will help address Asia's future needs, they said.

Companies like Siemens Water Technologies are doing research aimed at integrating desalination -- an energy-intensive process to purify seawater -- with solar power.

Rodman said encouraging people to change their consumption patterns of water and energy by helping them understand the link between the two is equally important.

"Gone are the days when water is independent from energy," he said.

Scarce water a growing concern for Norway's sovereign fund
Stockholm (AFP) Aug 24, 2011 - Norway's state pension fund, recently ranked the largest sovereign wealth fund in the world, cautioned Wednesday that water scarcity poses a growing risk for an increasing number of firms it invests in.

"Water was an important input and output factor at 865 companies the fund was invested in with 255 billion kroner ($47 billion, 33 billion euros) at the end of 2010," the Norwegian fund said in a statement at the World Water Week conference in Stockholm.

The fund, which contains nearly all Norwegian state revenues from the country's lucrative oil sector, invests in about 8,400 companies worldwide and was worth some 3.01 trillion kroner at the end of last year.

"Water is an important input factor at many of the companies the fund invests in but water is not an infinite resource," Magdalena Kettis, who is head of social and environmental issues for the fund, said in the statement.

"On the contrary, water may become an increasing cost that hurts profitability at many companies. This may in turn affect the fund's investments," she said.

The fund, which was created in the beginning of the 1990s to help finance Norway's generous welfare state system once the oil wells run dry, said it had for the first time conducted an evaluation of companies' water management risk reporting, assessing how 432 of the firms it invested in last year fulfilled nine criteria for reporting on water-related risks.

"The companies scored an average 2.7 out of a maximum nine points. A total of 131 companies scored zero, while 10 companies got top marks," the fund said.

According to Kettis, the results show that "far too few companies provide adequate information on water as a risk factor, particularly in their supply chains."

The fund concluded that "companies with inadequate water management face significant operational risks such as supply interruptions and higher treatment costs," pointing out that poor water management can also "lead to liability for damages or the loss of licences and permits.

"Access to the quantity and quality of water needed for production, as well as more stringent requirements for wastewater emissions, may impact the results of an increasing number of companies in the future," it said.
