Response to OP Forum message.
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. |

For reference, the above message is a reply to a message where: Perhaps crab eaters here will be concerned with a report from Scotland's Heriot-Watt University. Their studies indicate the electromagnetic fields from undersea cables bringing power ashore would be impacting their local crab populations. Underwater cables stop crabs in their tracks Click Here Dr. Alastair Lyndon, from Heriot-Watt University, said: “Underwater cables emit an electromagnetic field. When it’s at a strength of 500 microTeslas and above, which is about five percent of the strength of a fridge door magnet, the crabs seem to be attracted to it and just sit still." Consequences from the changes in the crabs' behavior include: less foraging for food, less seeking a mate, & changes in their blood chemistry, making them more susceptible to bacterial infection. Those brown crabs are the UK’s second most valuable crustacean catch, and the most valuable inshore catch.-- not very different than the blue crabs here. Seems the local folks could be quite angry if our blue crabs are impacted. |
