Paper – Dr. C. (Kees) le Pair Analyses Wind Power

More of an engineering paper than a science paper.
This analysis takes everything into account and discovers, from the actual data, that the modern Dutch windmills actually cause more consumption of fossil fuels, not less.

He does, however, debunk the theory that they use more energy to be built than they ever produce.

Energy costs of construction and installation, § 6
Wind turbines are considerable units. They require energy for their constituents, their construction, their foundation and their installation. One of the firms actually doing this type of work figured it out. (See ref. 5. Note 13.) It boils down to an amount of energy equal to the assumed production of the wind turbine during a period of 1½ year.
This energy investment has to be ‘written off’ during the whole life time of the installation. This according to wind supporters is supposed to be around 25 year. We have seen recently that a whole windpark in the Netherlands with that supposed life time had to be renewed after 12 year. Subsidy regulations applied by the government are based on a write off in 15 year. That is the period we deem realistic.
We shall incorporate the energy costs factor in our subsequent calculations with a life time of 15 years. To appease the wind fans, we’ll add a line based on 30 year. “

Electricity in The Netherlands.
Wind turbines increase fossil fuel consumption & CO2 emission.
C. le Pair

First we describe the models presently used by others to calculate fuel saving and reduction of CO2 emission through wind developments. These models are incomplete. Neglected factors diminish the calculated savings.
Using wind data from a normal windy day in the Netherlands it will be shown that wind developments of various sizes cause extra fuel consumption instead of fuel saving, when compared to electricity production with modern high-efficiency gas turbines only. We demonstrate that such losses occur.
Factors taken into account are: low thermal efficiency at low power; cycling of back up generators; energy needed to build and to install wind turbines; energy needed for cabling and net adaptation; increase of fuel consumption through partial replacement of efficient generators by low-efficiency, fast reacting OCGTs.
