The Crown Estate has published its seventh annual Offshore Wind Operational report. Published on Thursday 11 April, the report said offshore wind supplied 8% of the UK’s total estimated electricity generation, reducing carbon emissions by 12mn tonnes. The report also said that at the end of 2018 there were 1,931 fully operational offshore wind turbines on the UK seabed (equivalent to 43% of the European total) with a further 992 under construction. Also, over 2018, only China built more offshore wind capacity than the UK. Additionally, The Crown Estate highlighted the construction completed at the Walney Extension in the Irish Sea. 167 TB of survey content is now uploaded to the Marine Data Exchange (MDE), The Crown Estate said.
