Wind Power

The 630-MW London Array is now online and generating

Phase one of the London Array usurped the UK's Greater Gabbard to become the largest operational offshore wind farm in the world when its final turbine (its 175th) was commissioned on Saturday afternoon. Though construction was completed back in December, it is only now that all of the farm's turbines are supplying the UK's national grid with electrical power. The array has a total capacity of 630 MW.  Read More

Wind energy may be one of the more sustainable sources of power available, but the spinning blades of conventional wind turbines require regular maintenance and have attracted criticism from bird lovers. That might explain why we've seen wind turbine prototypes that enclose the blades in a chamber or replace them entirely with a disc-like system. But researchers in the Netherlands set out to eliminate the need for a mechanical component entirely and created the EWICON, a bladeless wind turbine with no moving parts that produces electricity using charged water droplets.  Read More

Not having a section devoted to cures for insomnia, Gizmag tends to pass over press releases about investment agreements. Tuesday's announcement that the Bank of Tokyo-Mitsubishi UFJ (BTMU) is to find somewhere in the order of US$ 2 billion for the Cape Wind is extremely interesting, however, as it means the U.S. should finally build its first offshore wind farm, with construction slated to commence before the year's end.  Read More

Bloomberg analysts say electricity generation from new wind farms is cheaper than new coal...

In 2008, the Garnaut Climate Change Review ranked Australia as the highest per capita emitter of greenhouse gases of any OECD country and amongst the highest in the world. One of the reasons for the country's high carbon footprint is its reliance on coal for electricity generation – 54 percent of it, according to the Australian Coal Association. But a new study by Bloomberg New Energy Finance (BNEF) points to a cleaner energy future with the claim that unsubsidized renewable energy is now a cheaper option for electricity generation than new coal- or gas-fired power stations.  Read More

The regeneration of Cermak Road includes new sidewalks with permanent wind/solar powered p...

A streetscape that includes natural landscaping, bicycle lanes, wind powered lighting, storm water diversion for irrigation, drought-resistant native plants and innovative “smog-eating” concrete has earned Cermak road in Chicago the title of “greenest Street in America” according to the Chicago Department of Transport (CDOT). Opened in October 2012, the first phase two mile stretch is part of the Blue Island/Cermak Sustainable Streetscape project which was introduced in 2009 with the aim of reducing overall energy usage by 42 percent.  Read More

GE's fabric-covered blade is reminiscent of the fabric-covered wings used on World War I f...

In a bid to help shape the inexorable march toward more efficient wind power, General Electric Power and Water is developing a new fabric-covered wind turbine blade which promises to cut the cost of wind turbine manufacture significantly, while also allowing a larger blade size, and facilitating easier transportation.  Read More

The Aquarius Eco Ship concept based on the EnergySail technology that uses solar panels em...

In the 400 years or so leading up to the adoption of steam power in the 19th century, sailing ships ruled the waves. In an effort to cut increasing fuel costs and reduce emissions, sails are set to once again prove their worth. But unlike the sails proposed by B9 Shipping and the Wind Challenger Project, Japan-based Eco Marine Power (EMP) is developing sails with an even more modern twist. Rather than just harnessing the power of the wind, EMP’s EnergySail can be fitted with solar panels to also harness solar power.  Read More

The Saphonian bladeless wind turbine draws inspiration from the design of a ship's sails

Tunisian green energy startup Saphon Energy has created a new bladeless wind turbine which draws inspiration from the design of a ship’s sails, and promises to convert the kinetic energy of the wind into electricity at up to double the efficiency – and half the cost – of a typical wind turbine.  Read More

Despite offering numerous advantages over its rotating brethren, most notably the ability to reach the high-speed winds found at higher altitudes, kite-based energy systems are yet to really get off the ground in a meaningful way. But things are looking up. Earlier this year, NASA revealed it is investigating ways to improve the aerodynamics and autonomous flight control of kites for power generation applications, and now Berlin-based wind energy developer NTS GmbH has teamed with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) to make their own kite energy system concept a reality.  Read More

Canadian startup Harvistor has tested its DARWIND5 vertical axis wind turbine and says it ...

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT). Designed by Harvistor, it comes with a promise of more oomph than existing models for small-scale wind power generation. According to the company, recent tests showed that its technology can achieve 35 percent more kilowatt hours per year than current VAWTs for the same sweep area, besides operating at 25 percent lower heights than similarly priced market leaders.  Read More
