From the US.

Renewable & free ey? ;D Yet still require fossil fuels to build them, lubricate them & actually run with diesel motors, these giant windmills. What a farce. Refuelling_the_Wind_Turbines.jpg (87 KB | 2

(Whiners?) I 'smelt' a lot of 'hot air' from Gnads, so I checked: (google) No, wind farms do not require fossil fuels to keep them running (spinning) when the wind is not blowing. When the wind stops, the turbines stop, and they simply wait for the wind to return. While some myths suggest that natural gas or diesel engines keep turbines spinning to prevent damage, this is not true; using fossil fuels to turn turbines would be inefficient and wasteful. Try again. Maybe a community not connected to the grid, relying on a (somewhat distant) wind turbine for power, might choose to power the local grid by spinning the turbine via a deisel generator (hence your photo) to reduce the noise of a diesel generator located in the community itself, though I'm not sure if that is feasible. |

You are confused Gnads. Wind turbines do not use diesel to generate electricity when the wind is not blowing. They would empty those tanks in a few seconds if they did.

Yes they do, just not for the grid. It is to stop the bearings false brinelling. |

You should stop relying on google. From Google AI - "AI Overview How to prevent false brinelling in rolling-element bearings Wind turbine brinelling, specifically false brinelling, is a common bearing failure in pitch and yaw systems caused by vibration-induced wear and corrosion during standstill or low-speed oscillation. It causes roller-spaced indentations and abrasive debris, leading to reduced efficiency and component failure. Prevention involves ensuring proper lubrication, minimizing stagnant periods, and optimizing load distribution. " So how do you minimize "stagnant periods"? ::) |

Turbine shafts are usually kept rolling at 3-7rpm with turning motor on a bed of hydraulic oil using jacking pumps, when they do stop then they are turned a quarter of a rotation on a regular basis.

i suppose it's better than turning them by hand. ;) |

Fair enough, if you want to be pedantic about it, but it is still not the turbine that generates the electricity. Even conventional power stations require power when they are not generating power. But still not something for Gnads to blow his mind over. |

Gnads was too confused to actually say anything. I know of at least one coal fired power station that ran into trouble because they needed mains power to start back up, but the gird was down, because the power station was down.... Funnily enough, they had the same solution as the wind turbines in the OP. |

No weiners - as in dickheads. It's a bit of an Americanism but I thought you being a knowledgeable man of the world would get the inference? Obviously not. Then you refute the claim without a shred of evidence. How typical. Quote:
Now dickhead - no one said they powered the wind turbine - that would be just stupid. But they are used for a variety of reasons in the operation of a wind turbine. That said I stand by the article I posted that they are a part of wind turbine operations whether in temp start up, maintenance or to assist with systems when it's too cold. There should be no fossil fuel back up or assistance for any part of so called "renewables" operations. |

Never said they did. But they are used in conjunction with various operational aspects. You green weiners are all off on a typical tangent of misreading what has been said. |

If you are trying to say that Gnads went a little hysterical and started a new thread with lots of crayons over a trivial non-issue, I agree with you. That is the point I was trying to make. If you are trying to say something else, perhaps you should come out and say it. Don't be shy. I'm sure you aren't as confused as Gnads. |

Now they do. Funny thing is, they are just like the wind turbines that Gnads is getting all worked up over, for reasons he cannot bring himself to state. |
