Scientists challenge economics of storing renewable energy

By - September 11, 2013 3 Pictures
True or false: solar and wind power are freely available and clean, and thus should always be stored when they generate more energy than the grid can use? It's easy to assume that renewable energy should never be turned off, but scientists at Stanford have done the math to find the break-even point where storing energy is better than "wasting," or curtailing, that energy, and their findings aren't necessarily as you'd think.

National Grid report challenges wind energy critics

By - June 25, 2013 3 Pictures
Squirreled away beneath a recent Telegraph report on the subtleties of badger-culling in the UK was this intriguing morsel of wind energy news, which would seem to challenge the idea that intermittent energy sources such as wind play havoc with grid management. For the 23,700 gigawatt-hours of electrical energy generated by wind in the UK between April 2011 and September 2012, only 22 GWh of electrical energy from fossil fuels "was needed to fill the gaps when the wind didn't blow," it reports. Gizmag contacted the UK National Grid to find out the details. Read More

Dodgy wind? Why "innovative" turbines are often anything but

Virtually every week there are articles about new and innovative methods for harvesting wind energy. And every week more megawatts of capacity from three-blade horizontal-axis wind turbines (HAWT) becomes operational, despite all of the contenders. Why aren't these innovative new products knocking the iconic HAWT off its perch? Is it possible to tell which are likely to be viable? These eight points are a useful way to assess which technology has potential, and which are likely just hot air. Read More

Google aims to take wind power to new heights with acquisition of Makani Power

By - May 27, 2013 9 Pictures
Having already put its Google Wallet where its mouth by backing a solar power tower plant in California to the tune of US$168 million, Google has now turned to wind power. According to a report from Bloomberg Businessweek, the search giant has acquired Makani Power, a California-based startup whose Airborne Wind Turbine (AWT) technology first caught our interest in 2011.

Strawscraper concept calls for a wind energy-harvesting toupee

By - May 23, 2013 4 Pictures
Despite being the most common renewable energy technologies, solar panels and wind turbines still have their shortcomings. Particularly when it comes to the urban environment. Lack of space and concerns about noise are just two problems with integrating them into city settings in an unobtrusive way. That's why Belatchew Arkitekter wants to try a different approach with its Strawscraper concept, which proposes transforming the Söder Torn building in Stockholm into an urban wind farm by covering it in piezoelectric fibers.

UGE replaces 4K wind turbine with mysterious mid-range VisionAIR

By - May 22, 2013 7 Pictures
Urban Green Energy (UGE) recently unveiled its newest vertical-axis wind turbine, the VisionAIR, as part of an installation at the Beijing International Garden Expo. The company confirmed to Gizmag that the VisionAIR is replacing its former 4K turbine, last seen adorning the top of an EV charging station, as its standard mid-sized option for customers. Compared with the previous model, the new turbine's design aims for better efficiency at moderate wind speeds, which UGE plans to integrate with its hybrid energy projects. Read More
