EVERY little helps - especially in the war against global warming.

Now supermarket giant Tesco is planning to enhance its green credentials by installing another set of wind turbines in York.

The firm has already got the go-ahead to put up turbines at its Askham Bar store, and now wants to do the same in the car park of its Clifton Moor branch.

A Tesco spokesman said the venture was part of its community plan, looking at ways the firm could reduce its carbon footprint and be a "good neighbour".

He added: "Our investment in wind turbines forms part of our plan to cut energy use and comes from our £100 million Sustainable Technology Fund to find more practical ways to use renewable energy.

"If we get the go ahead the turbines, which are inaudible, will help meet the energy needs and lower the carbon footprint of the store so we hope customers are as excited about this as we are and hope it demonstrates in a clear way our commitment to tackling climate change."

Similar turbines are being placed at Tesco stores around the country, in a partnership between the retailer and energy consultants TNEI Services.

At Clifton Moor, the firm plans to install two turbines, each 10.6 metres high and with a rotor diameter of 3.3 metres.

York councillor and environmental champion Christian Vassie said: "I would certainly welcome it.

"I know wind turbines are controversial for some but as fuel prices have gone up over $140 a barrel, it becomes ever-more important that we show a commitment to moving beyond the age of fossil fuels.

"If Tesco want to join us, that's great."

He said, however, that the main way of cutting down on needless energy use was to develop well-insulated buildings, and he said Tesco should look to emulate City of York Council's eco-depot when they were building shops in future.

"Green energy starts with insulation," he said.

"Getting them to build their next store like our eco-depot would be a great boost."

The roll-out of the six kilowatt Ropatec turbines in Tesco stores began in the north east, and has since gone national.

In the right conditions, each turbine generates enough energy to power four houses for a year.

TNEI and Tesco have been running the project since 2006. Having assessed sites for suitability, they are now managing the programme through to installation of the turbines.
