Danish Wind Turbine Repowering
The September edition of Energy World magazine has reported that
Siemens will supply 13 wind turbines, each with a capacity of 2.3MW and a rotor diameter of 93 meters, to a wind farm in Jutland, Denmark.
These will replace 77 older turbines and is the first major project within the Danish Government's repowering programme. Within the next few years, about 800 older turbines are to be replaced with fewer but more powerful ones.
Farmland birds still chirpy despite wind turbines
Wind turbines may not threaten bird populations as severely as ornithologists had feared. A growing body of evidence suggests that many birds are not bothered by the presence of giant spinning turbine blades.
The latest study, led by Mark Whittingham of Newcastle University, UK, suggests that agricultural lands could be a good place to set up the energy generators of the future without much fear for the effect on the local bird population.
Whittingham's colleague Claire Devereux led a series of surveys on the farmland surrounding two wind farms in East Anglia, in the southeast of England. On 11 occasions in January and February 2007, they walked through the farmlands, counting and identifying birds as they flushed them out of fields and hedgerows.
They found that all the species – including several listed on the Red List of endangered species – were found in equal numbers across the area, whether they were within 150 metres or 750 metres of the turbines.
