Offshore wind energy is the renewable energy obtained by taking advantage of the force of the wind that is produced on the high seas, where it reaches a higher and more constant speed than on land due to the absence of barriers. In order to make the most of this resource, big wind turbines are installed that are seated on the seabed and equipped with the latest technical innovations.
Wind farms sited in bodies of water have more electricity generation potential per amount of capacity installed in comparision to the onshore wind .
Unlike the typical use of the term “”offshore”” in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. Presently, floating wind turbines for deeper waters are in the early phase of development and deployment. The total worldwide offshore wind power capacity is 35.3 gigawatt (GW) of which United Kingdom (29%), China (28%) and Germany (22%) account for more than 75% of the global installed capacity.
The 1.2 GW Hornsea Project One in the United Kingdom is the world’s largest offshore wind farm.
