Rubber trailing edge flaps could result in quieter, more productive wind farms

If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge
– a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s Risoe DTU National Laboratory for Sustainable Energy tell us that such blades can flex by up to six meters [...]

Harvesting Energy From Nature’s Motions

By taking advantage of the vagaries of the natural world, Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life.
Energy harvesting is the process of converting one form of energy, such as motion, into another form of energy, in this case electricity. Strategies [...]

Can Wind Power Be Stored?

Wind farms typically generate most of their energy at night, so how do you bottle that power to meet demand that is highest during the day?
Wind farms typically generate most of their energy at night, when most electricity demand is lowest. So a lot of that “green” energy is wasted.
So the big question [...]

The Answer to China’s Future Energy Demands May Be Blowing in the Wind

Wind power is growing by leaps and bounds in China and might one day supply a significant portion of the country’s electricity needs–but not until it surmounts a host of challenges

Australia wind farm gets go-ahead

Approval has been given for Australia’s biggest wind farm to be built near Broken Hill in New South Wales.
Almost 600 turbines will generate enough electricity for more than 400,000 homes.
A forest of giant turbines will emerge from the red dust of the Australian outback near the isolated town famous for its lead and [...]
