moving turbines around
Hello, sorry this is not about the article, but I figured one of you may know this... If wind patterns can change over time, is it possible that at some point some wind farm would have to be moved because it ceased to generate enough electricity due to a wind slowdown? Would moving these things be so expensive as to make the entire ordeal unprofitable? You will note in my contribution history that I asked about wind currents recently (wp:ref). Thanks!

Kite-System Wind Turbines
Some editors may resolve the article missing this sector of wind turbines: kite-system based wind turbines. Generators are either flown or based in ground stations. Energy-kite system wind turbines mine upper stronger and steadier and thicker sectors of the wind gradient. 68.123.232.27 (talk) 03:18, 9 March 2017 (UTC)
- The article mainly covers production turbines, with some allowance for experimental ones. Kite turbines are experimental, and covered in Airborne wind turbine and others, and partially in Unconventional wind turbines, linked from this article. As new types become common, we can include them in proportion to their notability. TGCP (talk) 10:40, 9 March 2017 (UTC)
Possibly merge with windmill?
I don't see much difference between a windmill and wind turbine. Am I missing anything? Could we possibly merge windmill with wind turbine? Llightex (talk) 13:49, 17 May 2017 (UTC)
- Windmill is the parent article, of which Wind turbine is a subsection. Each article is well defined, well referenced, with plenty of content, but little overlap, as suggested by wp:Split. Compare with Napoleon Bonaparte and Joséphine de Beauharnais which also have overlap and diverse content. Or Engine and internal combustion engine and four-stroke engine and W16 engine, or...

- Oppose the historical context of the two terms is very clear, and coincident with their function. Windmills worked machinery beneath them, wind turbines generated electricity for use elsewhere. Andy Dingley (talk) 18:44, 17 May 2017 (UTC)
- Oppose as currently defined the wind turbine generates electrical power, so it's a type of windmill.GliderMaven (talk) 18:52, 17 May 2017 (UTC)
wind turbines and their problems
I am disgusted that Wikipedia cannot tell the truth about wind turbines. They are NOT green Genie 81au (talk) 03:35, 21 July 2017 (UTC)
- Be Bold. Cite it and write it. If you have reliable sources, please add whatever additional environmental impacts you can describe. --Wtshymanski (talk) 04:36, 21 July 2017 (UTC)
Efficiency
Just went on a tour of the local wind farm. Can someone expand on the efficiency section how the wind turbine generates power at varying wind speeds. The gearbox is apparently a fixed ratio, and power can only be generated when the blades turn at 16 rpm. It takes a minimum of 4 m/sec wind to turn the blades, but maximum power isn't until 13 m/s. Across this range of windspeeds, I assume the blades are feathered to maintain 16 rpm. At wind speeds above 13 m/s, I was told the turbine wastes excess wind. And why not have a variable gear ratio or transmission to allow a constant generator speed across a wide variety of wind speeds? Surely the stator electromagnet is variable, and can be increased to increase power output when the wind increases. At windspeeds above 25 m/s the turbine is stopped to prevent damage. What? Why can't there blades be feathered more at higher wind speeds to maintain 16 rpm and continue generating power? What an I missing here? I hope someone knowledgeable can expand this page to better explain efficiency across varying wind speeds. Tom Elwood Tomelwood (talk) 00:15, 25 October 2017 (UTC)
- This should be explained in the article, but the problem is variable ratio gearboxes are costly. It seems likely to me that the value of any extra energy collected wouldn't pay for the extra cost. Some variable-speed turbines use power electronics to convert varying generator frequency to the utility frequency, but these are rare, again, I suspect, because of cost. Lots of economics drivers for wind turbine operation, but then this is true of any installation, just more visible when you put it on a stick 100 metres in the air! --Wtshymanski (talk) 03:12, 25 October 2017 (UTC)
How do wind turbines concentrate energy?
This sounds a lot like pseudoscience babble to me. Can someone expand on this, maybe? If not, this sentence should just be deleted. I don't have access to the source, so if anyone does, please share!
