It’s an uncomfortable dilemma that has cast a long shadow over the sustainability credentials of a green form of energy.
For while wind turbines may project a carbon friendly image, when it comes to their manufacture, the steel, concrete, and plastics that go into making them take their toll on the environment.
While disposing of them at the end of their life poses additional problems: blades made from fibreglass and carbon fibre are particularly tricky to recycle, meaning they tend to end up in landfill.
