The government has high hopes for the expansion of offshore wind farms. But the construction sites are in a state of chaos: Wind turbines off the North Sea island of Borkum are currently rotating without being connected to the grid. The connection cable will probably not be finished until next year. In the meantime, the turbines are being run with diesel fuel to prevent them from rusting.
