The largest offshore wind farm to date has officially opened off of the Cumbrian coast in the Irish Sea and it has the ability to power 590,000 homes. The 659-megawatt Walney Extension takes up an area roughly the size of 20,000 soccer pitches and is made of 87 wind turbines. "The UK is the global leader in offshore wind and Walney Extension showcases the industry's incredible success story," said Matthew Wright, the UK managing director at Ørsted, the Danish company that developed the wind farm. "The project, completed on time and within budget, also marks another important step towards Ørsted's vision of a world that runs entirely on green energy."
