  None of these are in the oceans i believe. Instead they're using a sea that's between UK and mainland europe It shouldn't be a deal breaker, but doing the same on oceanic water will have it's own challenges with significantly higher wind variance and more flotsam dangers

  You claim of offshore wind being “cheap” relies on data from the north sea. A region of: - no freezing water, no icebergs - few, low intensity storms - shallow seas (often less than 100 m) - surrounded by wealthy nations with large population centres The argument does not hold and does not transfer well.

Behold, the Haliade X - 14MW offshore turbine which costs a little bit more than $14mln, but boasts a capacity factor of 60%+: https://www.offshorewind.biz/2020/09/21/rystad-energy-less-is-more-if-using-14-mw-turbines/ https://www.offshorewind.biz/2020/09/21/rystad-energy-less-i...

https://www.irena.org/Publications/2022/Jul/Renewable-Power-Generation-Costs-in-2021 https://www.irena.org/Publications/2022/Jul/Renewable-Power-... It's coming down. Though massive supply shortages and failure of a bunch of companies to hedge against commodity prices needed to fulfil budgets are going to be pretty rough for anyone who isn't China for a few years. Note how much more Japan's renewables cost than world median. The reasons aren't just policy -- Japan has ben dealt a uniquely terrible hand for renewables matched maybe by Slovak Republic (which at least has close allies to trade with).
