This dataset contains a set of zones and points representing plausible locations for offshore wind farms and individual turbines to have been built in the North Sea by the years 2030, 2040, and 2050, based off the national ambitions announced up to summer 2024. This version (version 3) is a major revision. Many wind farm zones and most turbines have moved. Column names have changed. See readme.pdf for further information and a changelog. A full description of how these coordinates were arrived at is currently under development as a journal article, and once it is available this readme will be updated to link to it. Check the "latest version" link in Zenodo to see if this has already happened. If using this version, please cite the dataset directly using the title and authors above and DOI 10.5281/zenodo.14222865 Please do not use "OSW zones.png" for serious work; use the underlying data instead. The image is included so as to give a useful preview in Zenodo.
