On a clear day, beachgoers in Egmond aan Zee can stand on the sand and count them: thirty-six white columns rising out of the North Sea, blades turning in a country that has been arguing with the wind for a thousand years. The Dutch built their first windmills to drain water. They built these to capture electricity. The principle is the same; the scale has changed. Offshore Windpark Egmond aan Zee was the country's first large-scale offshore wind farm, and when Prince Willem-Alexander cut the ribbon in April 2007, he was opening more than a power station.

Researchers tracked harbour porpois...

That number sounds modest now - newer North Sea projects measure their output in the gigawatts - but in 2007 it was a serious contribution to the Netherlands' renewable supply...

Then in March 2021, Shell bought Vattenfall's stake too, taking full ownership of the farm it had once shared. That same year Vestas began a refurbishment programme to extend the turbines' working life...
