The world’s largest offshore wind farm, the Lynn & Inner Dowsing, is set to provide 194 MW of power to the National Grid after completion this year. The Government wants energy companies to build 33 gigawatts of offshore wind farms by 2020.

The MV Resolution is the world's first purpose-built vessel for installing offshore wind farms. It uses its six massive legs, each half the length of a football pitch, to hoist itself out of the water at a rate of a metre per minute to create a stable platform. The turbines are secured approximately 25m below the North Sea. Some 70 crew live onboard the 130m by 38m vessel, which can carry up to 10 wind turbines measuring 100m high, almost 100m in diameter from the blade tips and weighing 260 tonnes each.

Each turbine can power 2,500 homes, with the whole wind farm eventually able to supply 140,000 homes.
