After just two months of operation technical problems have forced the blades of the world's largest offshore wind farm to stop turning. ...The wind farm has not been producing energy since last weekend and Dong Energy, which owns the wind farm, is losing approximately 1.1 million kroner each day the turbines stand still.

Wind turbine blades rip loose near Esbjerg and southwestern Sweden, one landing on a hiking path A malfunction on a Vestas wind turbine in the town of Falkenberg on Sweden's southwest coast could have resulted in tragedy, as one of the structure's large blades flew off and landed on a track used by hikers.

There are much cheaper ways to reduce carbon dioxide emissions than subsidizing renewable energies. CO2 abatement costs of PV are estimated to be as high as $1,050 per ton, while those of wind power are estimated at $80 per ton. By contrast, the current price of emissions certificates on the European emissions trading scheme is only 13.4 (Euro) per ton. ...Moreover, the prevailing coexistence of the EEG and emissions trading under the European Trading Scheme (ETS) means that the increased use of renewable energy technologies generally attains no additional emission reductions beyond those achieved by ETS alone.

Danish Wind Industry Association managing director Jan Hylleberg said ‘Our surveys show there's a huge desire in the councils to construct more windmills ...however, the energy gained from any new wind turbines would almost be offset by the planned removal of older and malfunctioning ones by 2020.

The German army has identified a series of wind park projects as a threat to national security and blocked investments worth 1.5 billion euros because it fears spinning wind turbines will interfere with its radar systems. The Bundeswehr has launched an investigation into the impact of the wind turbines planned for northern Germany's coastal area amid concerns they could compromise air defense -- because they could in theory provide a shield for enemy aircraft.

The Liberal Party wants to cut state funding for land-based wind turbines in favour of financing biogas, hydrogen and solar cell development. Several parties oppose the idea. ...Party group chairman Kristian Thulesen Dahl said consumers had paid huge additional charges on their electric bills for almost three decades, based on an ideological desire to promote the development of wind turbines.

Massive wind turbines seem to be killing more and more migratory bats, prompting research into these neglected creatures and efforts to minimize the toll. ...The deaths have led to a flurry of research on migratory bats and their behavior. "The problem with bats and wind energy has pushed a lot of work that wouldn't have occurred otherwise," says Edward Arnett of the Austin, Texas-based nonprofit Bat Conservation International. Indeed, at a January conference in Berlin on migratory bats, wind farms were a dominant theme. Scientists are racing to figure out what brings the bats in contact with wind turbines, and what can be done to save them.

Danish company Vestas Windsystems, the owners of a wind turbine factory on the Isle of Wight have fenced off the entrance to the site, where about 25 staff are on the third day of a sit-in. ...The company said the factory was being closed next week due to reduced demand for wind turbines in northern Europe. ... A spokeswoman for the Department of Energy and Climate Change said the plant made blades for the US market which were not the right specification for onshore or offshore wind farms in the UK.

Residents near Dortmund were evacuated this week after the ground collapsed around a geothermal heat pump, while in another German town, almost 190 buildings have now been damaged by a geothermal project gone awry.

The six offshore wind turbines that REpower Systems began erecting near Germany's coast in 2004 make their older cousins look like pinwheels. Each one has three 61.5-meter blades, which in a good breeze make one revolution every 5 seconds, producing 5 megawatts of electric power. Inspired by Germany's bold vision for capturing offshore wind energy, these majestic machines are designed to withstand anything the famously unforgiving North Sea can dish out. And yet, these turbines have never felt the spray of salt water.

Fresh concerns have emerged over the future of BP's alternative energy business after a fire broke out at one of the company's largest solar power installations in Germany. The incident on June 21 destroyed nearly 200 sq m of one of the world's largest roof-mounted solar panel arrays on a warehouse complex in Bürstadt, near Mannheim.

As much as 100 billion euros ($143 billion) in planned investments in German offshore wind farms are at risk as developers struggle to get funding, jeopardizing the deepest emissions cuts in the European Union. Bochum's municipal utility expects its first wind park to be delayed by up to two years, Managing Director Bernd Wilmert said. HEAG Suedhessische Energie AG, a regional energy supplier known as HSE, had to go to twice as many banks as it would have needed last year to finance a 1.3 billion-euro North Sea wind farm, Chief Executive Officer Albert Filbert said.

German savings banks are handing out more loans to renewable-energy projects as corporate rivals retreat from financing the world's biggest solar-panel market. The 438 savings banks financed 45 percent of the 5.3 billion euros ($7 billion) invested in solar and wind power projects in 2008, while loans from major corporate lenders including Deutsche Bank AG shrank to 0.8 percent.

Hundreds of workers at one of the south's flagship companies have today been told they will lose their jobs. Workers at Vestas, which has plants in Southampton and the Isle of Wight were this morning called into hear the shock news that the company is closing down its operations in the UK.

The economic crisis has slowed the market for wind turbines and has resulted in Vestas expecting to cut jobs. According to Vestas CEO Ditlev Engel in an initial Q1 report, the company is expected to lay off some 1,900 employees, primarily in Denmark and the United Kingdom.

German chancellor Angela Merkel has laid the foundation for a "milestone" renewable energy plant that answers the big question surrounding wind energy: what happens when it isn't windy? ...Some renewable energy experts have expressed doubts that the electrolysis will be as effective as planned and warn that the technology is a long way from being market-ready. ..."The technology is very elaborate and very expensive," says Dr Peter Schäfer of the Jülich research centre, which operated a similar hydrogen storage system powered by solar cells.

Danish wind turbines are now producing so much energy that they may have to be stopped at night in order to avoid excess production duties. ..."When prices go negative, wind turbines will probably have equipment installed so that you can reduce production," Marketing Manager Nicolaj Nørgaard Petersen tells Jyllands-Posten.

Offshore wind-energy installations in Northern Europe have lost appeal among financiers because of increased costs and difficulties in building and running equipment miles at sea, a German banker said. Many lenders have stopped providing credit for installations that are anchored to the ocean floor, said Thiess Harder-Heun, a director at Deutsche Kreditbank AG, which has financed construction of about 700 wind turbines over the past decade.

New figures show the country is lagging behind other European countries when it comes to wind power capacity Denmark risks losing its position as the leading European wind energy nation ...Seventeen percent of Danish electricity is produced by wind power, which is still the highest level in Europe, but Germany is catching up with 10 percent. ...Wind power currently accounts for six percent of the total national energy usage.
