Sweeping distance rules for onshore wind could further reduce already scarce land resources and impede reaching the wind expansion necessary for Germany’s renewable energy targets, a new study by the country’s environmental agency (UBA) found.
According to the wind turbine manufacturer, a lightning strike could have been the reason why the rotor blade broke loose.
Wind turbines for power generation should actually produce more electricity with increasing wind strength. However, this is exactly what they often do not do, which has confused experts for years. The puzzle could already have been solved in 2001 thanks to a new study: dead insects that stick to wind turbines should be responsible for the low yield.
Several roads were closed Monday morning after a wind turbine in the Hahnweiler / VG Baumholder wind farm experienced a blade failure.
“This is now the 3rd German onshore wind auction in a row that’s been under-subscribed,” explained WindEurope CEO Giles Dickson. “It’s clear the permitting process is not fit for purpose. It’s taking longer and longer to get a permit. The Bundesländer are reluctant to identify new locations for wind farms. And even if wind farms do get a permit, many then get caught up in legal disputes, which is pushing up costs.
The Federal Agency for Nature Conservation makes an ecological absurdity of the energy transition that anyone can see: the protection of the world's climate destroys the native nature.
In the district of Uelzen, the blade of a wind turbine broke off during a storm and fell to the ground. An investgation is called for to determine the cause of the incident.
Germany saw a sharp fall in the number of new onshore wind turbines installed last year, industry groups said on Tuesday, and warned there was little prospect of a recovery without government help.
A study by the RWI - Leibniz Institute for Economic Research shows that wind turbines can lead to falling prices of single family homes in the immediate vicinity. The value of a house one kilometer away from a wind turbine drops on average by a good 7 percent. For the study, the RWI has evaluated almost 3 million sales offers
If the annual energy balance for renewables is more positive from year to year, then such celebration is based on a very one-sided view of pure production volumes. Little is said about the contribution of renewables to a reliable power supply.
A spectacular accident on Monday morning: In a field between Gau-Bickelheim and Wallertheim near the A61 motorway, the almost 55-meter-long and ten-ton blade of a wind turbine was broken off shortly before 8 o'clock and crashed onto an adjacent field. Persons were not injured in the incident, fire department and police secured the accident site.
This small increase was reflected in its power generation figures, as renewables produced 6.2TWh between 1 January and 30 September in 2017, and 6.3TWh this year. However, Innogy explained that "particularly low wind levels, especially in the second and third quarters of 2018 in the UK and Germany, led to reduced utilisation of existing plants".
Medical and scientific evidence is increasing that not only some animals, but also humans are able to perceive infrasound below the hearing threshold. This is not surprising actually, because "infrasound is an energy," explains Prof. Vahl, "And every energy has physical effects, whether you hear it or not."
Proposals to allow states to set their own setback rules and to abolish wind farms' privileges under German building laws have been presented to the federal council. North Rhine-Westphalia and Brandenburg’s suggestions were discussed in the country's upper house, the Bundesrat, on 19 October and could be voted on in December, according to the German wind energy association (BWE).
A police spokesman reported that the fire initially broke out in the nacelle at around 3 o'clock on Friday morning and spread to the entire turbine. One blade of the wind turbine fell off after a short time while large parts of a second blade followed. Although the third blade did not burn, it threatened to fall after the nacelle was largely destroyed.
Wind turbine manufacturer, Juwi, won permission to erect twelve wind turbines in Reesdorfer Heide near Beelitz. Wind power opponents and the city have tried to prevent the project for years.
Erecting a few wind turbines on privatized, once communist farmland doesn't entitle Germany to claw back potentially lucrative power earnings, a top appeal court has ruled. It's voided part of a 2005 land sales contract.
Baur calculates: Since 2016, there have been 16 fires, 15 blade and nacelle accidents and 4 tower damages involving wind turbines in Germany. With tons of equipment and high rotor speeds, there is a "high risk potential for people and buildings in the area".
If extrapolated to all of Britain’s wind farms it would mean 80,000 die each year from colliding with the blades. The number increased with blade length with some individual turbines responsible for the deaths of five bats each month.
The mystery of why more than 80,000 bats are killed by wind turbines in the UK each year may finally have been solved. Scientists found the winged creatures are naturally drawn to sources of red light – an attraction that can confuse them on migration routes.
