Will London Win A Green Medal?

With London aiming to be the greenest Olympics ever, judgement day is approaching. Some progress is already evident, many derelict buildings have been removed, the River Lea has been opened up, with the hope of otters returning and over 2 million tonnes of soil has been cleaned of contaminants. Water in underground aquifers is being pumped out, cleaned and returned, the amount of building materials used has been reduced and grey water recycling will take place e.g. swimming pool water used to flush toilets. However, not everything has gone smoothly so far, plans for a giant turbine did not materialise and now only 11% of all energy will be renewable (as apposed to the planned 20%).
