North Sea Wind Power Hub is a proposed energy island complex to be built in the middle of the North Sea as part of a European system for sustainable electricity. One or more “Power Link” artificial islands will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea, just outside the continental shelf of the United Kingdom and near the point where the borders between the territorial waters of Netherlands, Germany, and Denmark come together. Dutch, German, and Danish electrical grid operators are cooperating in this project to help develop a cluster of offshore wind parks with a capacity of several gigawatts, with interconnections to the North Sea countries. Undersea cables will make international trade in electricity possible.The scale of this plan is impressive. The first island and surrounding turbines should generate around 30 Gigawatts of power; with a chain of islands that could eventually rise to 100 GW, enough for 100 million people. By comparison the largest wind power farm in the world today generates 0.63 GW. All of this infrastructure would be out of sight of land.
According to this plan, the first artificial island will have an area of 6 square kilometers. Thousands of wind turbines will be placed around the island, with short alternating-current links to the island. On the island itself, power converters will change the alternating current to direct current that will be carried to the mainland via undersea cables. The project is to be completed around 2050.

The North Sea Wind Power Hub
Dogger Bank. Building islands is expensive even in seas only a few meters deep, but building wind turbines and other infrastructure on land is so much cheaper than building it in water that the idea might still pay off. Ars Technica:
