What are the key takeaways from the World Economic Forum’s latest report on energy? One, global energy demand is showing no signs of slowing down, despite “peak driving” having arrived already in the US and Europe. Two, if we’re going [...]
With water stresses already at high levels in many parts of the world and not expected to ease in 2013, a number of innovators are trying new technologies to produce, purify and conserve this critical resource. New solutions will be [...]
From space, our planet might look like a “big blue marble” rich with water. On the ground, though, reality is different: water use in many parts of the world has become unsustainable, threatening not only local populations but global agriculture [...]
Most forms of energy we produce also require us to use water, often lots of water. Think of all the water needed to cool nuclear reactors, for example, or to generate steam to drive turbines in coal-fired power plants. Hydropower, [...]
This year’s World Water Day is focused on the most essential way in which we use water: to produce the food we eat. As the United Nations reminds us today, water and food security are inextricably linked. But so too [...]
Just as smart electricity meters are touted as a way to better control energy consumption and waste, smart water meters promise to help cities around the world stem losses due to everything from aging, leaky pipes to outright theft. A [...]
It’s been said that water is the next oil … as in, it’s the next resource we’ll find increasingly harder and more costly to use. That presents a growing challenge not only for individual users, but for the water companies [...]
Energy and water are linked in many ways, though we don’t always give much thought to the connections. A lot of water, for example, is used in producing electricity … whether it’s to provide cooling at nuclear power plants or [...]
Scientists have known for a while about the water-purifying properties of seeds from Moringa olfeira, the so-called “miracle tree” that’s native to northwest India but can grow in many other parts of the world. But past approaches to using the [...]
It’s hard to know whether to take this as good news or bad news: the US National Research Council (NRC) says we might soon worry less about water shortages thanks to technology advances that would let us turn municipal wastewater [...]
