Recycling wind turbines

Making wind power really green

The development of wind power promises much in terms of providing us with renewable energy for the future and wind turbines could be the most effective way to harness that power. 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.

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 minimize any potential negative impact of their use.
