The organizing committee for the 2012 London Olympics and the National grid are planning to make the games carbon neutral. How will the committee will do this? Well basically they are deciding on using bio-fuels which will be home-grown. There are also looking whether a single wind turbine could be added to the scheme. As for bio-fuels I doubt it will work cause this will affect other important crops in the UK and would lead to a downfall in the UK economy. Anyways to know more visit the source.
