The world's biggest offshore wind farm has been officially opened by the Prime Minister.
The London Array is situated 12 miles off Clacton in Essex. The £1.8 billion windfarm covers 95 square miles and can create enough energy to power three quarters of the homes in Essex.
The project is being hailed as good for jobs, particularly after claims the East could produce up to 75% of the country's energy supply in the future.
But there are some that say it's not so good for taxpayers, with critics claiming green energy will cost each household more than £600 a year by 2020.

David Cameron said Britain is a "great place to invest" as he heralded the opening of the world's largest offshore wind farm close to the coast of Essex.
Mr Cameron described London Array, in the outer Thames Estuary, as a "big win for Britain" which proves the country is capable of delivering large-scale projects.
The Prime Minister spoke at the inauguration of the fully functioning wind farm which reached full capacity earlier this year with the commissioning of its 175th and final turbine.
All of its turbines export power to the national grid and could produce enough green electricity to power nearly half a million homes a year.
