Hundreds of wind turbine blades line banks of Humber as world's largest offshore windfarm generates first power

Electricity has been generated from what is soon to become the world's largest offshore windfarm for the first time - after the first four massive turbines were shipped from Hull last month.

Around 500 turbine blades, which each measure 75 metres in length and were made at the Siemens Gamesa factory in Hull, have been lined up on the banks of the Humber ready to be shipped out to the site of Hornsea Project One.

The windfarm in the North Sea - off the coast of Yorkshire and Lincolnshire - will cover an area five-times the size of Hull and generate power for a million homes when its fully operational next year.
