Nothing whatsoever about the tower the turbine stands on, nor the construction of the roads, nor the building of the foundations.

The roads could certainly be used again and I expect the platform could as well. Even the tower could potentially be used again when the time comes to replace the parts that have used up their functional life. The 26,000 to 41,000 tons in carbon emissions it took to construct would not need to be expended over and over, some of that would be at most a periodic cost.
