Wind turbines: the whole truth.
IV1. The electricity yields.
The total amount of kilowatt-hours consumed in the Netherlands per year, delivered by plants to the Netherlands from within and from abroad, amounts to a yearly average power of around 13,000 MW or 13,000,000 kW (in 2006 and 2007). Please remember or make a note of this number as it is extremely important: 13,000,000 kW.
The Dutch electricity generation from 1990 till 2007.

About 15% of this is imported from abroad because for many years the Netherlands built too few power plants. More than half of these imports are produced by nuclear power plants, which is why it is particularly hypocritical to say that we do not want to use nuclear energy, because we have been using that already for many years. (About three times the energy produced by our small nuclear power plant in Borssele comes from abroad).
Let us now compare the yield of the many big Wind turbines placed in the Netherlands and offshore near Egmond aan Zee with a maximum installed power, for each turbine, of 3,000 kW, with the required production power for the Netherlands of 13,000,000 kW. Supposing a very high average production factor of 36% offshore, that 3,000 kW wind turbine, because of those inevitable and unpredictable fluctuations, will produce an average power of 0.36 x 3,000 = 1,080 kW, representing a 1,080 / 13,000,000 = 0.000,083rd part of the production power required for the Netherlands.
Just 19 of the 1204 Wind Turbines of 3000kW to be placed at
sea to compensate yearly electricity consumption increase in the
Netherlands.
Let's relate this to the yearly average increase of electricity consumption in the Netherlands.
Over the last three years (2005 through 2007) this increase was on average 1%, this means that in the Netherlands, just to compensate the yearly increase of electricity consumption 1204 of these enormous wind turbines have to be placed at sea. Year after year.
And an even smaller part the Netherlands' total energy consumption.
Just 39 of the 1733 Wind Turbines of 3000kW to be placed on
land to compensate the yearly electricity consumption increase in the
Netherlands.
In the case of onshore Wind turbines the yields are even more miserable: assuming a seldom reached production factor of 25%, a 3,000 kW wind turbine produces 0.25 x 3,000 = 750 kW. That represents 750 / 13,000,000 = 0.000,058 or just about six parts in a hundred thousand of the electricity production that we need. To produce one per cent of our consumption, 175 of these enormous Wind turbines are required. With their nacelle at about 100 meters above ground and a propeller circle of about 75 meters.
Just to compensate the yearly increase of electricity consumption, 1733 of these enormous wind turbines have to be placed on land. Year after year.
But behold! These are just the up-to-date big Wind turbines being installed in the Netherlands nowadays. We have not mentioned the 1,828 Wind turbines, with an average capacity, like those built in the previous years and whose aggregate production in 2006 represented no more than 2.4% of our national requirements of 13,000,000kW-year, as published by the CBS, the Dutch Central Office of Statistics. According to these data, in 2006 the average production per windturbine was (0.024 / 1,828 = 0.000,013), a 13 millionth's part of our electricity consumption. None of the wind energy promoters will ever reveal or explain this to you. It is always carefully withheld.
We must never forget how this minimum amount of kilowatt hours is produced with hundreds of power alterations; onshore as well as offshore.
