Has anyone seen any sort of "exit-strategy" for wind-farms when they reach the end of their service-life?
The companies which erected them will have long since ceased to exist, and the energy-provider who harvests the output will most likely have a clause written into the contract absolving them from the expense and inconvenience of dismantling them and recycling whatever is recyclable (quite a bit of copper in the windings and armatures, for a start).
I'd be interested to now if anyone is thinking that far ahead. A nascent industry, perhaps?
