Danish researchers now suggest that in order to assess the overall environmental impact of wind power, however, the finite lifespan of wind turbines and the need to replace and recycle them must be taken into account. Such an assessment will help policy makers and the industry to develop the green credentials of wind power more effectively.
Writing today in the Inderscience publication, International Journal of Technology, Policy and Management, the researchers describe a prospective case study for managing environmental aspects of wind turbines. Their suggested plan for assessing the overall impact of installing and operating wind turbines should be adopted by the industry and policy makers, they say.
Wind turbines are one of the most environmentally sound technologies for producing electricity, explain the researchers. However, the removal and recycling phase of wind turbines has been identified as a blind spot in assessing their overall environmental impact. Most studies have ignored this phase and focused entirely on their operation and in some cases the production and installation of wind turbines.
Foresight and innovation analysts Per Dannemand Andersen and Mads Borup working with wind energy expert Thomas Krogh have devised a method for mapping and mitigating the negative environmental impacts of wind turbines which considers the future removal and recycling of offshore wind turbines up to the year 2050. By combining life-cycle assessment and taking into account future developments in this area of renewable energy, the team hopes that the wind power industry will be able to minimise any potential negative impact of their use.
"Because the wind-turbine industry is relatively young, there is only a limited amount of practical experience on the removal and recycling of wind turbines," Dannemand Andersen says, "It is likely to take more than 20 years before a substantial amount of practical experience regarding the dismantling, separation, recycling, disposal, etc., of wind-power systems is gained."
The present study has developed an interactive and process-oriented method for investigating the environmental impact of wind turbines removal and recycling. The team hopes that the industry will adopt their approach and so find ways to reduce any negative impacts of wind power.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
