This isn't an answer. If a country was to rely on windmills alone for its energy, you might need several days worth of storage to keep the country running. A period of tatl calm extending over an enture country - even one as smal as the Netherlands - is remarkably improbable. It's also irrelevant to any discussion of the way we'd get our energy if we were to stop burning fossil carbon, because we wouldn't rely on windmills alone, but on a mix of windpower, solar power, hydrolelectric power and probably the osmotic pressure generator that are now showing up as prototypes, as well as the occasional nuclear power station and probably a few residual fossil-carbon-fueled power stations that sequestered their CO2 output into under-ground or undersea storage Our current grid could survive without storage with up to 20% of our power coming from windmills. There are small-scale installations - on islands for example - where a day's worth of storage is enough to let the system tolerate a much higher windmill contribution http://www.energypulse.net/centers/article/article_display.cfm?a_id=1164 And every clean kilojoule that we generate from wnd at the moment is saves us the CO2 emission from the fossil-carbon we didn't have to burn. > >> And the same green nut cases that vote for 'clean' energy vote against wi= > >ndmills because of 'horizon pollution', > >> and because those kill birds, and .. and .. ? > > >Too true.

I passed NT2 (Dutch as a second language) in reading, listening and speaking someyears ago. I didn't pass on my written Dutch - nobody has ever wanted me to write Dutch so I've never had enough practice to get rid of the minor grammatical errors. > Many Dutch also speak English. Almost everybody. This meant that everybody could read my reports, and minutes of meetings (in Dutch) in English, while many of the customers didn't speak or read Dutch. Had I written my reports in Dutch, they would have had to be translated back into English for all the overseas customers who don't know Dutch and don't have any compelling reason to learn it. And I have learned other languages - French, German, and a little Russian. I've never used any of them enough to be truly fluent, and learning Dutch compleltely destroyed my capacity to speak German, though I now understand it a bit better than I used to. -- Bill Sloman, Nijmegen

The human cost of serious CO2 reduction would be immense, especially in the poorest countries. Climate researchers have an overpowering moral obligation to be honest and keep an open mind. John
