I don't know where to start with this one so I'm just going to write and see where it takes me.
To me, wind turbines seem like the best possible way for Scotland to 'go green'. For them to be financially viable though they need to be big (at the moment). The technology isn't efficient enough yet to make a turbine cheaply that will pay for itself in under five years. For them to make money they need to be mass produced. I live within about 15 miles of two wind farms, including one of the largest in europe.
Offshore windfarms however are a different story altogether. The scale of the proposed farms that I knew about was two maybe three hundred turbines per site (at least). Now, depending on how far out they are I suspect that the combined drone from three hundred wind driven generators would equal that of a small army and as such agree that they are a bad idea for the island.
I also agree that they could affect fishing zones if an exclusion is set up around them, again this would be bad for the island.
If it's managed well though the Island could seek to benefit - if they play a hard bargain.
These companies generally don't give a toss because their throwing large amounts of money (read "the governments money") into renewable energy sources. As such they would probably be willing to offer financial incentives and or community development schemes to benefit the island to balance out the perceived disadvantages of the farms.
If the project goes ahead I also reckon that there could be scope for increased business on the island with workers etc etc (however I'm expecting this would be unwanted given my experience of past problems with the shop running dry on occasion...).
The thing that completely confuses me though is this... The sea around Scotland is effing HUGE! Why the bloody hell do they need ANY farms within five miles of the coast at all. Why not stick the farm 7 miles to the south of Tiree, far enough away that they'll be a pinprick on the horizon and shouldn't really affect the lives of people on the island that much (apart from the possible fishing boat restrictions that is).....
I'd like to see the farms go ahead from a Scottish eco stand point but I don't want to see them having a bad effect on peoples lives. I doubt they will harm the environment or wildlife in any way as they are passive, I.E have no by products and don't do anything to change the habitat around them.
Will be keen to see where this one ends up though!
