Windturbines: the whole truth.
IV1. The electricity yields.
The total amount of kilowatt-hours consumed in the Netherlands per year, is now being produced by all plants that deliver to the Netherlands from within and from abroad, with 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.
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 use 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 windturbines as placed nowadays in the Netherlands and offshore near Egmond aan Zee with a maximum installed power 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 jerks, 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. Or expressed in other terms: the eight hundredthousandth part of our electricity consumption. And an even smaller part our the Netherlands' total energy consumption.
In the case of onshore windturbines the yields are even more miserable: counting with a seldom reached production factor of 25%, a 3,000 kW wind turbine produces with 0.25 x 3,000 = 750 kW. That represents 750 / 13,000,000 = 0.000,058 or just about a six hundredthousandth part of the electricity production that we need. For one per cent of our consumption, 175 of these enormous windturbines are required. With their nacelle at about 100 meters above ground and a propeller circle of about 75 meters.
But behold! These are just the up-to-date big windturbines placed in the Netherlands nowadays. We have not mentioned the 1,828 windturbines, 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 was published on the electricity yields 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 parts 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 kWH's are produced with hundreds of power alterations. Onshore as well as offshore.
