Climate Change Big Picture  ( a work in progress ).

The London Array is an offshore wind farm in the Thames Estuary in the United Kingdom. With a nameplate capacity of 630 megawatts (MW), it is the world’s largest offshore wind farm. The first foundation was installed in March 2011 and phase I, consisting of 175 turbines delivering a capacity of 630 MW, was confirmed fully operational on 8 April 2013. The wind farm is named the London Array because it supplies electric power to parts of Greater London.

The wind farm has an offshore area of about 100 km2 (38.6 sq miles) and can generate enough power for nearly half a million UK homes a year. CO2 savings are estimated at 925,000 tonnes a year.
