RE: BAsplit from IAG EU wants the split8 Mar 2022 10:23
That Express piece is the classic propaganda BS that has mislead so many, it is a sales pitch to flog more turbines on false promises of self-sufficiency.
"During the recent Storm Eunice day-ahead energy prices actually fell as wind produced nearly 50 percent of the UK's electricity."
A bare faced lie!
Even texts that try and play down the high wind problem by using terms such as hurricanes can not hide the truth, turbine efficiency drops over 25 mph because the blades are pitched to waste wind energy and the turbine must be stopped at 55 mph, and that is only for the most advanced. Many have a much lower furling speed. So to claim the turbines were over producing during storm Eunice is a bare faced lie. You will not hear the lie bing 'fact checked' or challenged across mainstream media because it would instantly expose what a con these turbines are. Very expensive lumps of spinning metal that cost a fortune to maintain.
"2. Wind Speed too High – Furling Speed
As wind speed increases, the wind turbine will reach what is called its ‘rated speed’. This is the wind speed at which the turbine generates maximum electricity, and for a modern grid-scale wind turbine, this is about 25mph4 (Beaufort Wind Force 6 – Strong Breeze).
If the wind speed continues to increase, the blades spin faster and faster, and this is not desirable. The turbine needs to be kept within its rated speed for maximum generation efficiency. This is done by slowing down the blades using a process called pitch control or blade feathering. Blade feathering is when the angle of the turbine blades is twisted so that they pick up less of the wind and so keep rotating at the rated speed even as the wind speed increases.
If the wind speed continues to increase, all wind turbines have a maximum wind speed above which they cannot operate. This is called the turbine’s ‘furling speed’. If the wind speed exceeds the furling speed (for example in a hurricane) the turbine has to be shut down to prevent the blades getting damaged. A modern grid-scale wind turbine has a furling speed of about 55mph (Beaufort Wind Force 10 – Storm). Once the wind speed drops back down safely below the furling speed, the turbine can be allowed to restart and continue generating electricity."
