Two 44-metre blades have broken on a Vestas V90 3MW turbine commissioned at a Danish wind farm in December. The blades came off “approximately a third of the distance from the tip end” on Sunday at the site close to the town of Sæby in Northern Jutland, Vestas said.
Denmark is one of the world biggest producers of wind energy. 30% of its energy production is based on the wind turbines. But are there any consequences to be considered about the noise that these wind turbines produce? Are they harmful for the human health?
This paper examines the negative impacts of turbine view and noise on the sale of residential properties. The authors conclude that "noise and visual pollution from wind turbines have a considerable impact on nearby residential properties." and that "local residents who live in close proximity to these sustainable giants experience some very real negative externalities in the form of noise and visual pollution." The abstract and conclusion of the paper are posted below. The full paper can be accessed by clicking the links on this page.
Vestas grossly misrepresented investors about its revenues on pending contracts in 2009 and 2010. Vestas continuously prided itself on the continuous rise of its order book due to rising incoming “firm and unconditional” orders. The Company kept the market closely informed about these orders and tied its own guidance for future revenues and earnings to the evolution of the backlog. However, the evolution of the order book as announced by the company cannot be matched with actual deliveries. Orders that were announced as “firm and unconditional” seem to have left the order book without having given rise to deliveries (for an amount of approximately EUR 1.4 bn).
At least one green energy developer recognizes that these stimulus subsidy programs have a record of doing more harm than good, and he isn't reluctant to say why. Patrick Jenevein, CEO of the Dallas-based Tang Energy Group, posted a Wall Street Journal article arguing that "the sequester offers Washington a rare opportunity to roll back misguided subsidies and maybe help reverse wind power's stalling momentum."
Only a handful of companies have the qualifications and equipment to remove seafloor explosives -- the special ship required for it costs up to €200,000 per day ...the turbines are currently being powered by a diesel generator, because they need to continue moving to avoid gathering rust. Given the latest developments, Riffgat may be an energy drain, instead of an energy producer, for quite some time.
Vestas has filed lawsuits against the two Indian companies embroiled in the Danish company's row with former CFO Henrik Nørremark. Vestas has filed the lawsuits in New Delhi's high court against RRB Energy and ECO RRB for the return of money handed over by Norremark, in deals that were not sanctioned by the Danish company's board.
This open letter written by Mauri Johansson, MD, MHH, a specialist in Community and Occupational Medicine, reveals important information about the impacts of wind energy development on communities in Denmark and how these impacts are being exported to other countries.
Dong made clear its intention to sell onshore assets to fund offshore development in a new strategy and financial action plan published in February. ..."Our competences and capital will be deployed in offshore wind where we have a strong and differentiated competitive platform."
The powerful Danish wind industry in the last six years received over 80 billion, with the bulk of the money going to project owners and investors. At the same time, Danish electricity consumers paid $4.6 billion in so-called PSO charges last year for wind power. That figure has skyrocketed by 270 percent over the past five years.
A young eagle was cut in two by a spinning windmill in Skagen. Danish Ornithological Society is in turmoil and believes that poorly sited wind turbines may cost several birds. The dead bird with a wingspan of 2.25 meters was found on the ground Sunday morning.
The slain young eagle was likely one of the six white-tailed eagles in a row, "said Pedersen, who follows bird migration in Skagen daily.
Vestas Wind Systems A/S (VWS), the unprofitable Danish wind turbine maker, is fighting an attempt by investors to probe a change in its accounting policy that they say damaged the company's share price.
The wind turbine maker is halfway through a two-year push to cut its workforce by about 30 percent to 16,000 as it seeks to return to profitability following two years of losses. It's reduced its cost base by more than 250 million euros of the target for 400 million euros of cuts by the end of 2013.
The Danish Parliament favours the wind industry to a degree where the constitutional state is weakened. Ida Auken, Minister for the Environment, is so indifferent to facts that in a consultation she delivers 38 wrong answers, including the information that wind turbine noise does not disturb more than noise from any other source, and that the regulations are stricter for wind turbine noise than for any other noise.
I realized I had a story that was bigger than just the effectiveness of wind energy. You can like it or you can hate it-that isn't the point. What this is about is government and business rushing ahead with new technology without ever making sure it's safe. A car manufacturer would never get away with releasing a new model without extensive safety tests. Same goes for food, appliances-anything. And yet these machines just kept going up, and up, and up.
The documentary starts out in Alberta where wind energy has been a success ...It moves then to more densely populated rural Ontario where the reception to turbines hasn't been as welcome, and then to Denmark, once a poster-child for wind energy, where the relationship between residents and turbines has soured.
Local councillors in the city of Hvidovre are fuming that neighbouring Copenhagen plans to erect four wind turbines in a waterfront area on the border between the two cities. Hvidovre oppose the construction of the 148 metre wind turbines, four times the height of Copenhagen's Round Tower, arguing they will spoil the view from their new beach near Kalvebod Syd, while compromising an adjacent nature reserve.
The Renewable Energy Foundation published this research paper by Dr Gordon Hughes, Professor of Economics at the University of Edinburgh, on the performance over time of wind farms in the United Kingdom and Denmark. The paper can be downloaded by clicking the link(s) on this page. The UK and Danish data used in the analysis is also available below. The following summarizes the results of the research.
The government considered eight areas for the offshore parks but in the end chose only the six where local support was judged to be high enough. The areas ...will accept bids for 450 MW of commercial production and 50 MW of experimental turbines. The latter will receive a fixed price of 12 cents per kilowatt-hour
