Walney wind farm off the coast of Cumbria in the UK yesterday became the world’s largest offshore wind facility. One hundred and two turbines over 73 sq km (28 sq miles) provide a maximum output of 367.2 MW. It’s claimed the facility will provide enough power for about 320,000 homes – half as many again as the total number in Cumbria.

The project’s first phase, Walney 1, has been providing power since January 2011 from 51 137-meter-high (450-ft) turbines, each with a 107-m (350-ft) rotor diameter. The completed second phase, Walney 2, adds another 51 turbines of even greater size to the installation. These 150-m (492-ft) tall turbines have three 18-tonne (19.8-short ton) blades with a total diameter of 120 m (394 ft). Despite the differing dimensions, all turbines are Siemens-made 3.6 MW turbines. All told a single wind turbine weighs a hefty 550 tonnes (606 short tons). The Walney 2 installation was completed in an impressively tight six-month window.

By building a wind turbine to power a hydrogen production and fueling station, a little hamlet in Long Island is positioning itself as the bellwether for carbon-neutral transportation.

The town of Hempstead, New York on Long Island erected a 121 foot tall turbine last December on the township’s Department of Conservation and Waterways land to take advantage of powerful Atlantic winds and power the hydrogen and natural gas fueling station it built in 2009. The turbine can generate up to 180 megawatts of power per year, and presents an estimated hydrogen fuel and energy cost savings of $40,000 per year.

California is the nation’s most populous state, which helps make this landmark even more impressive: According to the LA Times, “Wind energy now supplies about 5% of California’s total electricity needs, or enough to power more than 400,000 households.”

That’s big news. California has effectively doubled its wind power capacity since 2002, and is now home to 4,000 MW. The state installed 921 MW last year alone, and is now ranked just behind Iowa and Texas in generating capacity.

The premise of value investing is to buy securities whose shares appear underpriced by some form of analysis. Warren Buffett is the strategy’s greatest adherent and also its greatest success story.

In the past six weeks, Buffett’s MidAmerican Energy Holdings Company has been on a renewable-energy investment spree, buying up the $2 billion Topaz Solar Farm, in Southern California; a 49 percent interest in the $1.8 billion Agua Caliente solar project, in Arizona; and, last week, another wind project acquisition in Illinois, which brings the company’s wind power portfolio to $6 billion.

After the Fukushima disaster wiped out the future of nuclear energy, wind energy has taken on a new swing: a wind turbine that could generate twice or even three times the energy that regular turbines put out so far.

Ever since March last year, a team at the Kyushu University have been testing their “Windlens” – turbine units with a capacity of 70 to 100 kW (blade diameter of 12.8) – in an attempt to bring down wind power costs so it can rival coal and nuclear energy.

The idea behind them is to introduce to the Japanese and eventually the global market a brand new wind turbine concept, since previous models left a lot of users and policy makers disappointed: the turbines were underdeveloped, which led to a short, inefficient and noisy life.

At least 400 megawatts of electricity from wind projects in Gharo and Jhimpir will be added to national grid by the end of current year (2012) which is being observed as the year for wind energy.

This was stated by the chief executive officer of Alternate Energy Development Board (AEDB) Arif Alauddin while talking to media at a reception organised by National Forum for Environment and Health (NFEH) here the other day.

He said that investment commitments of $500 million have been made for energy projects. Four wind projects were at advanced stage, while 12 projects have completed their financial close. They included Zorlu of Turkey, CWE of China, Three Gorges, Fauji Fertilizers, Fauji Foundation, Arif Habib and Lucky Cement, he added. He was of the opinion that 1,200 MW will be added to the national grid every year from 2013.

The WindFlip barge concept was designed to simplify the installation of offshore wind turbines and in the process has managed to be a solution that also cuts cost. Installing offshore wind turbines can be an expensive task — the process requires skilled technicians to assemble turbines at sea, and to anchor them at great depths. Alternatively, the WindFlip barge allows turbines to be assembled completely on shore, towed to their location, and then simply tipped into place — thus minimizing the need for expensive work at sea.

With the calendar year winding down, very nearly everyone, this site included, are putting out their year-in-review content—and the American Wind Energy Association is no different. It’s pretty easy to get down on US renewable energy policy if you’re just paying attention to the nonsense coming out of legislators bought and paid for by the polluting class, but there were some truly great milestones in US wind power in 2011.
