UK built half of Europe's offshore wind power in 2017

Capacity is growing fast and turbines getting bigger - some almost as large as the Shard

Britain accounted for more than half of the new offshore wind power capacity built in Europe last year, as the sector broke installation records across the continent.

The windfarms out in the North Sea and other shallow European waters are getting bigger in every sense. Soon turbines will almost be as large as the Shard, Europe's tallest building.
