Plans to build electricity-generating wind turbines at its two Tesco superstores have been scuppered by Hounslow Council.
The supermarket giant had requested planning permission to erect energy-saving turbines in the car parks of its stores Syon Lane, Osterley, and Mogden Lane, Isleworth, superstores, have been rejected
The machines would have generated enough energy to power the equivalent of four UK households per year, but councillors have refused permission despite council planning officers backing the plans.
Syon Councillor Jon Hardy said: "The amount of electricity generated would be quite small; by my calculation enough to power a single bar electric fire for a few hours a day."
However as one council officer pointed out, Tesco's own motto of "every little helps" is very appropriate when discussing the matter of energy saving.
Members of the Isleworth and Brentford area planning committee, refused the planning application on the grounds of visual intrusion, noise disturbance and inadequate power generation.
Tesco said it respects the decision but is "naturally disappointed". A spokesman added; "These modern efficient turbines do make a difference.
"It wont deter us from seeking alternative ways to lower our carbon footprint."
Had the application gone ahead each 10.6 meter high turbine would of generated about 1220Kwh of electricity a year and would of prevented on an annual basis, the emission of 655Kg of carbon dioxide into the atmosphere.
This is despite the fact that the nearest resident to the Mogden Lane turbine would have been 50 metres away and the nearest to the Syon Lane turbines, 60 meters, with sound levels at a minimum due to the lack of gearbox or brakes.
It is estimated that the sound to these nearest neighbours would of been 20dB quieter than trees on a windy day.
The decision was made even after officers reminded members that under London planning policies the council is 'obliged not to challenge applications for renewable energy regardless of their actual power output, and to support such applications if there would be no harm to townscape, value or neighbours.'
Officers recommendations were to approve the plans 'by virtue of providing renewable energy through wind generation' as well as 'help to reduce carbon emissions in the Borough.'
They also pointed out that wind turbines generate interest in and awareness of renewable energy as well as the energy itself.
"IBAC will always support genuine initiatives to protect the environment," said Cllr Hardy. "We hope that Tesco will make future attempts to reduce their carbon footprint, as one Member suggested, reducing the amount of plastic packaging would be a huge benefit."
