Offshore wind power plants are becoming more and more popular. Such powerful turbines are being drawn everywhere. But it is becoming increasingly clear that these are harmful to marine ecosystems. This is clear from a study. Once again, this so-called “climate protection” is not really “green”.
If climate fanatics have their way, more and more stretches of coast around the world will be fitted with offshore wind power plants. But the construction of these plants not only directly results in negative changes to the marine ecosystem, but the effects may be far more widespread than previously thought. Because giant wind turbines affect the food chain near the coast and also the regional climate near the coast.
A study by Helmholtz-Zentrum Heron, focusing on the effect of offshore wind farms on ocean dynamics and the weakening of the wind and the associated changes in the physical conditions of the affected North Sea regions, sheds light on this. A report from the Center states:
“Hearon Institute of Coastal Systems Study – Analysis and Modeling Simulates Weakening of Wind Speeds on the Leeward (Leeward) Side of the Parks. This phenomenon was recently documented by the Heron team whose study was published in the journal Nature (Akhtar et al., 2021). Turbines are the reason for the weakening of the wind. (…) They extract kinetic energy from the wind field to generate electricity. So-called atmospheric wake vortices occur on the downwind side of wind turbines. They are characterized by low wind speed, high pressure conditions and increased air turbulence. Under stable atmospheric conditions, the reduction in wind speed extends up to 70 km behind the wind farms.
Accordingly, the wake turbulence effects of these wind turbines affect the stratification of existing currents and seawater and thus alter the mean temperature and salinity distribution in these regions. It affects plankton and thus also affects the food chain in coastal areas. There is no mention of stray whales. Though the damage is yet to be assessed, sooner or later it will make itself felt. Because these changes will also affect regional atmospheric conditions – and thus coastal areas as well.
Apparently, none of those responsible have given the slightest thought to what such large offshore wind farms actually do in terms of wind currents. For example, if the wind blows inland, these systems slow it down, meaning that the normally cold ocean air is no longer able to penetrate inland. This also ensures slightly warmer weather there. Are climate junkies too clueless?
