The Hornsea 2 offshore wind farm on the UK east coast, which will be the world's largest operating offshore wind farm once fully operational in 2022, has produced its first power, says Danish energy firm Orsted. Spread across an area of 462 km², it will use 165 turbines from Siemens Gamesa, boast a capacity of more than 1.3 gigawatts, and power “well over” 1.3 million homes when finished. Between them, Hornsea 1 and 2 will provide enough power for well over 2.3 million homes. The UK is targeting 40 GW of capacity by 2030, and the European Union is targeting 300 GW of offshore wind by mid-century. While the US has some way to go, change is coming -- the Departments of Energy, Interior and Commerce wants to roll out 30 gigawatts of offshore wind by 2030.
