Denmark: public policy regarding loss of value to real property due to wind turbines

Lisa

January 01, 2009 5:16:51 AM

Denmark adopted this policy in 2008-2009 which requires developers to pay compensation for loss of value of real property following the erection of the wind turbine. A summary of the policy is cited below. The policy document detailing the process of determining loss and compensation can be accessed by downloading the file linked to this page. This information was obtained from the Danish Energy Agency website.

Risø DTU final report regarding Vestas windmill damage (Feb 22-23, 2008)

Following the catastrophic failure of two Vestas wind turbines on Feb 22 and 23, 2008, the Danish energy agency requested an investigation into the events. A report was produced by engineers at Risø DTU. Below is the report translated into English. The original report, in Danish, can be accessed by clicking on the link below. A video of one of the failures can be seen here: http://www.windaction.org/videos/14294 . It is important to note that the debris from the first turbine failure which occurred on February 22 spread as far as 700 meters away. Risø DTU is formerly a government research institution under the Danish Ministry of Science, Technology and Innovation.

Wind turbines more annoying than expected

The Windfarm perception project shows that the sound of wind turbines causes relatively much annoyance. The sound is perceived at relatively low levels and is thought to be more annoying than equally loud air or road traffic. This may be caused by the swishing character of the sound or because at night it does not decrease in strength -which is usually the case for traffic noise. Also in this study more disturbance of sleep occurs at the highest sound levels that occurred in this study. ...In the WINDFARM perception project, supervised by Frits van den Berg, the perception was investigated of modern, tall wind turbines by Dutch residents. The study shows that sound from wind farms is an important disadvantage of wind energy which in itself is positively appreciated by a majority of the participants.

Wind power in Denmark, 2006

Almost a fifth of the electricity produced annually in Denmark is generated by wind, yet only about 6% of the country’s electricity demand is satisfied directly from this source. Possibly two-thirds of its wind power output cannot be used to satisfy domestic needs at the moment of generation, and has to be exported (often at reduced prices) to preserve the integrity of the grid. Savings in carbon emissions are minimal. Public opposition and reduced subsidies have halted the deployment of on-shore wind turbines for the time being, but political and commercial interests are pressing to integrate much larger amounts of wind power into radically altered domestic and international transmission systems.

Less For More: The Rube Goldberg Nature of Industrial Wind Development

Rube Goldberg would admire the utter purity of the pretensions of wind technology in pursuit of a safer modern world, claiming to be saving the environment while wreaking havoc upon it. But even he might be astonished by the spin of wind industry spokesmen. Consider the comments made by the American Wind Industry Association.s Christina Real de Azua in the wake of the virtual nonperformance of California.s more than 13,000 wind turbines in mitigating the electricity crisis precipitated by last July.s .heat storm.. .You really don.t count on wind energy as capacity,. she said. .It is different from other technologies because it can.t be dispatched.. (84) The press reported her comments solemnly without question, without even a risible chortle. Because they perceive time to be running out on fossil fuels, and the lure of non-polluting wind power is so seductive, otherwise sensible people are promoting it at any cost, without investigating potential negative consequences-- and with no apparent knowledge of even recent environmental history or grid operations.

Eventually, the pedal of wishful thinking and political demagoguery will meet the renitent metal of reality in the form of the Second Law of Thermodynamics (85) and public resistance, as it has in Denmark and Germany. Ironically, support for industrial wind energy because of a desire for reductions in fossil-fueled power and their polluting emissions leads ineluctably to nuclear power, particularly under pressure of relentlessly increasing demand for reliable electricity. Environmentalists who demand dependable power generation at minimum environmental risk should take care about what they wish for, more aware that, with Rube Goldberg machines, the desired outcome is unlikely to be achieved. Subsidies given to industrial wind technology divert resources that could otherwise support effective measures, while uninformed rhetoric on its behalf distracts from the discourse.and political action-- necessary for achieving more enlightened policy.

International Experience With Implementing Wind Energy examines the relative costs, advantages and disadvantages of wind generation. In addition, the report explores infrastructure issues, public attitudes toward wind development, and the various policy instruments used to support the development of wind energy in countries that are leaders in implementing wind energy.
