Sandy - I am not sure what you are getting at. The Shetland windfarm's output (load or capacity factor) of 57% was an average output over a year. The Spanish output was 67% but that was for a specific point in time that day. Sometimes windfarms do produce 100% of their capacity. It just tends to be not very often or when the grid needs the power.

Still cold here in Highland Perthshire, ground still hard from the frosts last week, snow and sleet all yesterday and forecast is much the same for the next 5 days. http://www.metoffice.gov.uk/weather/uk/ta/finnart_forecast_weather.html Hope things are warmer in France.

NYT article on biofuels -

Days of Promise Fade for Ethanol in USA
MACON, Mo. — Five years ago, rural America was giddy for ethanol. Backed by government subsidies and mandates, hundreds of ethanol plants rose among the golden fields of the Corn Belt, bringing jobs and business to small towns, providing farmers with a new market for their crops and generating billions of dollars in revenue for the producers of this corn-based fuel blend.

Those days of promise and prosperity are vanishing...

Sandy,

Unfortunately I can't chase that until tomorrow but it does look odd.

"It says that 7469 MW corresponds to 33% of the total installed wind power."
That's in keeping with the figure I quoted ie 14GW equates to 67% of capacity. Spain has just over 21GW of wind turbine capacity.
On 13-Mar-2013 at 11:50 Spain's wind supplied 13616 MW, 65% of the 21GW. Good so far, but according to this

http://www.reuk.co.uk/Burradale-Wind-Farm-Shetland-Islands.htm

<B>The 3.68MW Burradale windfarm is located just a few miles outside Lerwick, the Shetland capital. Since opening in 2000, the turbines at this windfarm have had an average capacity factor of 52%, and in 2005 averaged an incredible world record 57.9%. These data certainly bode well for the future success of the proposed 600MW windfarm.</B>

I don't think things will have improved to such an extent that Spain's installed base, presumably across the entire country, can beat at record for a single, very windy location in 2005.

So what is going on.

"The Marcott-Shakun Dating Service"

".......As you see, there is a persistent decline in the alkenone reconstruction in the 20th century using published dates, but a 20th century increase using Marcott-Shakun dates. (It is taking all my will power not to make an obvious comment at this point.)...."

I could not possibly comment!

Has anybody mentioned this?

It says that 7469 MW corresponds to 33% of the total installed wind power.

Sandy,

Spain regularly achieves 14GW, which is 67% of capacity. Average over the year though is about 21%.

@Robin Guenier
Agree that wind is a waste of time though.

@David Porter cc /Robin Guenier / Martin A / Skiphil
Is that 20GW theoretical max or an achievable figure? If they manage 50% output then they need 28GW for the maximum I've seen. At a more realistic 30% then the installed base must be 40GW. The link Robin Guenier gave earlier
http://www.ree.es/ingles/sistema_electrico/pdf/infosis/sintesis_REE_2011_eng_v2.pdf

has in 2011 20GW of wind out of a total of 100GW,

Have they doubled the amount of wind potential during 2012, or am I missing something?
