I saw no mention of offshore wind Kwh in those sources.

The land based wind farms are likely 99+% of those Kwh production figures. And are far less costly to build & maintain than offshore. Yet the land based have their own problems: splitting and breaking off of the fibre glass blades, collapse of the towers, fires in the turbine units, & heath effects on nearby residents.

Extensive mechanical problems in the land based turbine mechanisms have caused big $$ losses to Siemens Gamesa (their turbine division), with $5.0-billion losses in 2023 and $2 billion expected in 2024.

For times when the wind isn't blowing there's the need for replacement power plants to be maintained raising the costs, as well as when there's significant mechanical failures. Such replacement power costs are routinely omitted/ hidden when the wind promoters make their cost comparisons. AND That produces a major mathematical falsehood.

Both the land based and offshore wind share that same mathematical flaw, when making cost comparisons.
