Wind turbines tested at Gunfleet Sands off Essex coast

Two prototype wind turbines, the biggest in the world, are being tested off the Essex coast.

The six megawatt (MW) turbines can generate almost twice as much electricity as the existing ones and have been built at Gunfleet Sands near Clacton.

The have been made by Siemens and installed by Dong Energy.
