One of the biggest offshore wind farms in the world has just started turning in the North Sea, off the coast of the Netherlands. Hidden over the horizon, the Gemini wind farm isn’t visible from the mainland or the neighboring islands, and is set to produce about 2.6 TWh of electricity every year.
Situated 85 km (53 miles) north of the coast of Groningen, the Gemini wind farm is made up of 150 turbines spread out across 68 sq km (26 sq mi). The spot was chosen because not only is it out of sight and out of mind for Netherlands residents, but the wind speeds in the area are consistently high, averaging about 36 km/h (22 mph). With a capacity of 600 MW, Gemini is the second largest offshore wind farm in the world, behind only the London Array.
