Blades in the harbour

As I drove the 15 km to work on this grey and uninspiring day I wondered what the day's photo would be. On sunny days it's easy but when the murk moves in it's more of a challenge!
Driving alongside the harbour I suddenly saw these huge wind-turbine blades lying there. Each one is about 50m long and as you can see broad and round at the base and thin and fragile looking at the tip.
Härnösand harbour is a regional center for the delivery of these huge machines which are destined for the tops of hills and tower above the forest to reach the "clean" air high up and avoid the turbulence of the tree tops.
Today 7% of Sweden's electricity comes from wind and I heard on the news this morning that it soon could be 25%.
