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.

Creating power from water. I bet when I say that you picture a damn or a large turbine being pushed by hundreds of thousands of gallons of water, all rushing at tremendous speeds. It is a cool, and accurate, image of how most power comes from water. That is not to say that it is the only way that power can come from water.

Increases in temperature as a result of climate change are mirrored in lake waters where temperatures are also on the rise. A new study, by Dr. Martin Dokulil, retired researcher from the Institute for Limnology at the University of Innsbruck in Austria, forecasts surface water temperatures in large Austrian lakes for 2050 and discusses the impact on the lakes' structure, function and water quality. The research is published online in Springer's journal Hydrobiologia.

During the last space shuttle flight, astronauts will test a new method for recycling 'used' water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future space explorers.

A new study has discovered viruses in almost 40 % of more than 1,400 bathing water samples collected from coastal and inland areas in 9 European countries. The findings, presented in the journal Water Research, suggest that the presence of infectious adenoviruses and noroviruses in water samples 'could pose a risk to health.'

The island nation of Singapore is aggressively promoting a solution to the water scarcity that vexes countries worldwide: recycling toilet water to drink.

In this month's Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of water, providing a possible solution to the problem of the world's ever-growing population demanding more and more fresh drinking water.

Scientists are monitoring a massive pool of fresh water in the Arctic Ocean that could spill into the Atlantic and potentially alter the ocean currents that bring Western Europe its moderate climate. The oceanographers said Tuesday April 5, 2011, the unusual accumulation has been caused by Siberian and Canadian rivers dumping more water into the Arctic, and from melting sea ice. Both are consequences of global warming.

A team of researchers, led by Dr. Yi Cui, of Stanford and Dr. Bruce Logan from Penn State University have succeeded in developing an entropy battery that pulls energy from the imbalance of salinity in fresh water and seawater. Their paper, published in Nano Letters, describes a deceptively simple process whereby an entropy battery is used to capture the energy that is naturally released when river water flows into the sea.

Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.

Britain has brought online a new desalination plant near London capable of providing the city with 150 million gallons (568 million litres) of water per day, should the need arise. At a cost of £270 ($445) million, and built over the past four years, the plant uses reverse osmosis to remove salt from the brackish water pumped in from the Thames Estuary, which it then pumps into local reservoirs, thus staving off the threat of drought.

What may be the world's largest chemistry experiment in history launched last week as part of the International Year of Chemistry 2011. The American Chemical Society (ACS) announced it will help support teachers and students who wish to participate in the experiment, "Water: A Chemical Solution," by sending volunteers to classrooms that need assistance.

Twenty former heads of state, including former US president Bill Clinton, warned Tuesday of an impending "water crisis" and agreed to establish a panel that will tackle a worldwide leadership gap on the issue.

Forest Service Southern Research Station (SRS) scientists recently used long-term data from the Coweeta Hydrological Laboratory (Coweeta) in Western North Carolina to examine the feasibility of managing forests for water supply under the changing weather conditions forecast for the future.

Many energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn. They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

Tim Berners-Lee, the man attributed to the creation of the internet, gave a speech at an MIT symposium and shared his two decades worth of internet knowledge with the crowd. He spoke about a wide variety of issues, from net neutrality, which he is supportive of, to mobile web access. Berners-Lee's words concerning web access raised a couple of eyebrows, and definitely raised the interest of this writer. "Access to the Web is now a human right" he continues, "It's possible to live without the Web. It's not possible to live without water. But if you've got water, then the difference between somebody who is connected to the Web and is part of the information society, and someone who (is not) is growing bigger and bigger."

More than one billion urban residents will face serious water shortages by 2050 as climate change worsens effects of urbanization, with Indian cities among the worst hit, a study said Monday.

It's ubiquitous. It's universal. And it's understood-not! Water's choices in a given situation often defy scientific predictions. When expected to bond with other water molecules, it shuns them. When expected to ignore a surface, it becomes deeply attached. However, research at Pacific Northwest National Laboratory has revealed why one of the simplest and most important molecules on the planet makes some of the decisions it does.

The Dalai Lama said Saturday that India should be seriously concerned about the melting of glaciers in the Tibetan plateau as millions of Indians use water that comes from there.

Himalayan villagers have won the backing of climate science for their suspicions that snow cover, water resources and the ecosystem are changing in their region, a study published Wednesday said.
