Dong Energy has dismantled the Vindeby offshore wind farm in southeast Denmark that was built in 1991 as the world’s first demonstration project to prove it was possible to generate green electricity at sea.

The offshore wind industry has since matured into one of the fastest-growing segments of renewable energy generation worldwide with a capacity of 16.1GW. Most of that is still concentrated in northern Europe, but offshore wind is rapidly spreading to Asian markets and the US.
