Lolland is flat and therefore has a high wind index. This makes the island an ideal location for wind turbines. In 1991, the world's first offshore wind farm was built off the coast of Lolland at Onsevig. 25 years later, it had served its time and was dismantled again. Old, worn-out turbines are being dismantled around the island and replaced with new, modern 150-meter tall turbines.
