Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

You forget the Sea on that assessment.

I'm not saying that the situation is bad for the US, just that it isn't that bad in Europe.

is a lot easier in Europe because the North Sea has very low water depths over huge surfaces. If it becoems necessary, you can build a LOT of wind farms in an area which is not very far from very big population centers.

Wind power is not yet the cheapest, but it gives us a wonderful hedge as the price will NOT increase once capacity is installed (cost at the time of installation can vary as raw materials to build the farms vary, but it's still not that resource intensive to build anyway).

Current plans are in the UK for offshore wind to provide 13% of total electricity by 2020. A lot of it is already permitted, or in the planning phase. And that's without a crash programme, just the current framework.

That is not only true of the North Seam it is true also of the Hudson Bay, Newfoundland and the US Eastern Seaboard
The edge of the Caribbean basin would work too, were it not for those pesky tropical cyclones.

There is a difference between depth below 100m and depth below 40m, in terms of how easy it is to build fixed structures there.

The North Sea is really a lot more convenient in that respect.

for failed rifts.

Let's remind everyone that during the last ice age people could walk to England across the North Sea shelf. Archaeologists generally suspect there were communities making a living on the shelf, before the rising tide washed them away.

And as of today, there are only 2(!) wind turbines developed specifically for offshore operation deployed in the North Sea.

This is in fact a huge resource waiting out there.

There are more than 10 large wind farms in operations - below only the bigger ones:

Denmark
Middelgrunden 40 MW (2001)
Horns Rev I 160 MW (2002)
Nysted-Roedsand 165 (2003)

UK
Barrow 90MW  Apr-06
Kentish Flats 90MW Nov-05
Scroby Sand 60MW Dec-04
North Hoyle 60MW Jul-04

Netherlands
NoordZeeWind 99MW (2006)

Lots more info in this this pedf presentation on offshore

The 2 turbines you refer to are the 5MW REpower turbines installed on the Beatrice project, I presume.

Yes, off course, all the others are onshore turbines tweaked to function at sea.

Jérôme forgot Arklow Bank in Ireland, which consists of developed-for-offshore 3.6 MW GE turbines.

I only took the big ones - that work. Alklow Bank has been an unending series of problems - so much so that GE has effectively abandoned this turbine model.

I knew of several technology-related delays before opening, and the lack of new orders for the model spoke volumes (as did the abandonment of any talk about the planned second phase of Arklow Bank), but is it off-line now?

They've stopped marketing it. They are working on a new model now, as far as I know.

Sorry, I meant Arklow Bank, not the turbine type. Is it still operational, or was the type such crap that Arklow Bank is idle?

By the way, have you heard anything about Vestas's plans for a biggie (V120)? there is total silence on that, too.
