I would have thought onshore designs might be more economic if produced from mass produced components capable of being transported by reasonably standard road vehicles - e.g. Max dimensions c. 15X3X5M and max weight c. 50 Tonnes per component? Is there a point at which bigger becomes more expensive per unit out put?
What are the estimated lifespans of these major components - given sea water corrosion, storm damage, wear and tear etc. - do they degrade beyond maintenance at some point? If they do, we will have a significant decommissioning cost and a significant carbon footprint over their lifespan. Do we know what this is compared to other power sources? notes from no w here
Won't go. Blades are much longer, they need special vehicles. But those exist. However, transport is only a very small part of the overall cost for onshore turbines. For offshore ones, I suspect the size of the foundation necessary and the construction cranes is a more relevant limitation than transport. *Lunatic*, n. One whose delusions are out of fashion.
