Re: Offshore wind news (4.00 / 6)

Momentary market penetration does not reflect how "competitive" it is. Change in market share does, however -- and wind's market share is increasing.

In addition, in some regions where there is both a good wind resource and a long history of wind power, like Denmark and Northern Germany, wind's share is up to 40%. It's double-digits in the entirety of both Spain and Portugal, too.

In detail with sources (4.00 / 5)

For states of Germany, here (pages 7 and 14) you find potential shares for installed wind in net electricity consumption [based on longtime average wind speeds and 2008 consumption; due to below average winds and significant new capacity added during the year, 2009's actual numbers must have been a tenth or so below these]. While Germany's Northernmost state Schleswig-Holstein indeed sports the 40% number I mentioned, I forgot that East German states catched up, with Sachsen-Anhalt leading at 47%. For all of Germany (see in German), wind's share was 6.5% (a slight drop due to below average winds).
I intended to say 40% for Western Denmark, but now see that I mis-remembered and it is not so uneven. For all of Denmark, in 2009, based on data here (Excel!), wind's share in net consumption (with losses) was 19.32%. (That number shall definitely pass 20% with the off-shore farm mentioned in the diary.) The monthly peak was 28.59% in November, and the low was 12.66% in April.
For much bigger Spain, here you can see that wind's share was 14.39% in 2009, with a monthly peak of 22.62% and a low of 9.63% (August).
In Portugal, as I diaried, wind's share in electricity consumption was 15.03% in 2009.

(November).

AEE also has this most interesting graph, on the evolution of the different production modes:

The strongest drop is shown by coal ("CARBÓN") -- in fact for the first time both wind ("ÉOLICA") and the sum of other feed-in-law supported renewables ("RESTO RÉGIMEN ESPECIAL") overtook it.
The strongest growth is from combined-cycle gas ("CICLO COMBINADO"), but it stopped recently
The most intermittent on a multi-year scale is hydropower.
