Well blow me down - wind energy is proven not to work! (Unless you have a non-stop gale, of course!)

This is another blow [excuse the pun] for the foolish notion that we can live for ever on power that costs nothing!  Whether they be multi-turbine wind farms on great pylons at vast expense or single machines on your roof, they don’t work!  

Just take this one - -  £1,900 plus considerable costs of installation [say £3,000 in total ? ] , to produce a maximum of 1kw when everything is perfect.  Most of the time it won’t be perfect and 500 watts would be generous.  With that amount of electricity it could only really be useful in the evenings to light the kichen or the living room - if the wind is blowing!   So perhaps you could get 180kw/hours  in the period of a quarterly electricity bill. at 12.59p a unit [my rate!]  So you might save around  £23 a quarter or £92 a year .  On that basis it would take 33 years to pay for itself (21 years for the turbine alone).  And the life of the turbine?  It’ll be much less than 21 years you can be sure.

However, this is ‘green’ economics where such calculations are regarded as blasphemy in the new religion.  

Haven’t had such a good laugh for ages.

DIY chain withdraws wind turbines from sale
DIY chain B&Q has withdrawn wind turbines from sale in its stores because they are not as efficient at producing energy as first thought.


By Christopher Hastings 

The company began selling the £1,900 micro-turbines at its 320 stores across Britain in October 2006.

It claimed the equipment would generate up to 1kW of electricity, wired directly into a main power supply, allowing households to reduce the amount of power they needed to buy from the National Grid.

But the firm has now withdrawn the product from its shelves after a survey by energy consultants Encraft warned that home turbines generated only a fraction of the energy promised by manufacturers and in some cases used more electricity than they produced.

The study, which tested different types of turbines in different locations, showed the worst performing devices provided less energy than needed for a conventional light bulb.

On average turbines surveyed could provide sufficient electricity to light an energy-efficient house, but this still only represented 5 per cent to 10 per cent of the manufacturer claims.

The retailer said it had decided to withdraw the turbines after many months of customer feedback.

A spokesman said: "The Encraft study suggests that B&Q's range of micro-turbines may not perform well enough to satisfy our customers expectations."

The store is understood to have sold hundreds of the machines since they went on sale. Micro-turbines became popular after David Cameron admited he had installed on the roof of his own home.

B&Q said the study had shown that turbines in urban areas were the least likely to perform well.

It added: "The vast majority of B&Q's customers live in highly urbanised areas, hence this particular finding is cause for concern for the company."
