A white elephant goes up in smoke
The wind energy industry is almost unique amongst industries in that it can grossly distort and exaggerate it's output and contribution to energy supply and Co2 reduction yet remain apparently totally detached from state accountability and its economic laws of supply and demand which-agriculture apart-underpins all industrial economies.
Now an energy expert has described as' nonsense' a claim by an energy company building a four turbine power plant in Cornwall that it will supply enough energy for 8000 homes.
Good Energy, which is installing the turbines at Delabole, says its figures are based on average household energy use by the Department of Energy (DoE).
But figures from the DoE put the figure at about 5,700 households, calculated by Professor Michael Jefferson.
The four new turbines will have a total combined capacity of 9.2MW (megawatts), enough to supply "over 7,800 homes" with electricity, says Good Energy.
It bases its calculation on 32% efficiency of the turbines and energy usage per home of 3,300kwh (kilowatt hours), a figure it says comes from the DoE and Ofgem.
Yet the DoE said while the figure of 3,300kwh was "acceptable", it based calculations for windfarms on 4,500kwh.
The larger energy use figure makes the actual number of houses supplied 5,731, said Professor Jefferson of the London Metropolitan Business School.
Mr Jefferson, a professor of International Business and Sustainability, told BBC News: "Never, ever, have I come across a figure as low as 3,300 kwh."
He said in an email to Good Energy: "Good Energy claim their Enercon turbines will power nearly 8,000 households.
"With respect, that must be nonsense."
