The first phase of the world's largest offshore windfarm is up and running. The final turbine at the London Array in the Thames Estuary has now been commissioned which means that all of them are exporting power to the national grid.
With all turbines now exporting power to the national grid, London Array is expected to produce enough green electricity to power nearly half a million homes a year.
Plans for a windfarm off the Sussex coast have moved a step closer. Energy company Eon which is proposing to build the site says it has listened to concerns from local residents and environmental groups and has changed the design. The revised proposals have been on display in Brighton.
Local residents will be able to have a say on the revised plans by visiting the website.
Charlotte Wilkins has been talking to Steve Ankers from the South Downs Society and Chris Tomlinson, the development manager.
