It is quite simple when using our common sense.
Let us compare Wind turbines with a "brilliant idea", that it must be possible to run electric trains using overhead lines which would have voltage at some times and none at other times, completely depending on the prevailing wind force. Or to recommend very costly cars and trucks with a fuel flow to the engine that would depend on wind speed.
Someone who sticks to such a thought must definitely be off his nut. Our entire government, including all its ministers, would consider a proposal for such trains and vehicles madness. They would not agree to provide subsidies for the construction of these technical monsters, and certainly not with subsidizing every kilometre these things would travel.
But why then should this be different from recommending Wind turbines for electricity generation, as these suffer from the same disadvantage? Do these not have a source of energy fully dependant on the random and unpredictable wind force? And do these not constitute a risk through the possible interruption of a function which is of such vital importance to our society as the reliable supply of electricity? But in the case of these machines, totally unfit for their job, they do give a subsidy for their construction and even another subsidy for their unreliable supply of a product of particularly bad quality.
What makes a judgment on these essentially foolish contraptions different from a judgment on wind energy? The difference consists in the fact that those silly trains and vehicles are not judged in the first place by "politics" and pre-selected people and agencies with a tendency to be heavily biaised by personal interests. On the contrary, that is exactly the case in issues related to wind energy.
There is a lot of money to be made from wind turbines, and a certain image to be gained by a so-called person of vision. The requirement for success is that one must be able to sell the story unscrupulously, and cleverly bring it on stage, enthralling the most credulous part of the public. From the facts just laid out, any person with wits will be able to form a fair judgment about the behaviour and usefulness of Wind turbines, and thus will understand that the general public is having dust thrown into its eyes by the propagandists of wind energy, including the government.
