Not quite accurate anymore. The UK was indeed the world leader from 2008 until around 2021, but has since fallen to second place behind China. China now has over 41 GW installed (>50% of global capacity), while the UK sits at ~15 GW (~22%). [1][2]

Still impressive for a country of that size, but "world leading" is technically no longer correct.

ps.: Per capita it's also not #1 — Denmark and the Netherlands both have higher offshore wind capacity per person.
