The symbolic structure will provide energy for housing and street lighting for about 20 years

A gigantic wind turbine is to be built on the site of the London 2012 Olympics.

The 130m high structure will be one of the tallest wind turbines in the UK. It would provide the energy equivalent of supplying 1200 homes a year.

The turbine will be situated in Eton Manor at the north end of the Olympic site, and would be operational for up to 20 years.

Construction is expected to start in 2008 subject to planning permission. The ODA said it It would be operational by 2010 at the latest.

London 2012 Organising Committee chair Seb Coe said: "The wind turbine will be a dramatic and iconic feature of the Olympic Park. It will provide a visible statement of our intent to make the Games as sustainable as possible, and is a significant part of our overall strategy and commitment to minimising the carbon footprint of the 2012 Olympic Games and Paralympic Games."
