Orphaned references in Wind power in the United States[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Wind power in the United States's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "EWEA 2013":

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT 13:05, 30 September 2014 (UTC)

Meteorolgy section - temp removal for editing discussion[edit]

 ==Wind energy meteorology==

The boundary layer wind, e.g. 100 m wind, is controlled by the wind condition in free atmosphere, perturbed by fast varying turbulence in the boundary layer. Strong winds in the free atmosphere lead to strong boundary layer winds near the surface, and consequently high instantaneous values for the capacity factors of wind turbines. The problem with the output from a single wind farm located in any particular region is that it is variable on time scales ranging from minutes to days posing difficulties for incorporating relevant outputs into an integrated power system. The high frequency variability of contributions from individual wind farms is determined mainly by locally generated small scale boundary layer. The low frequency variability is associated with the passage of transient waves in the atmosphere with a characteristic time scale of several days.[1] Moreover, the Central Plains region of US is under the influence of the large scale metrological transient waves. Electricity generated by one wind farm located in the Central Plains region is not independent of the electricity output from another wind facility in the same region.[1]

First of all, to my knowledge, there is no such thing as instantaneous capacity factors. This does not make sense. [EDIT: Actually it does, now that I've thought about it more.] Secondly, the phenomena which is being discussed doesn't appear to be specific to the United States. Hence the information may be better suited to the more general article Wind Power. Thirdly - the information in the paragraph(and possibly the article) seems merely to say that the output from wind farms in a region is correlated and not independent. This is not new info. and is mentioned in the Wind power article. It could be mentined in this article as well. Aflafla1 (talk) 04:27, 24 October 2014 (UTC

Ok, the following is my proposed revised text:
Winds in the Central plains region of the U.S. are variable on both short (minutes) and long (days) time scales. Variations in wind speed result in variations in power output from wind farms, which poses difficulties incorporating wind power into an integrated power system. Wind turbies are driven by boundary layer winds, those that occur near the surface of the earth, at around 300 feet. Boundry layer winds are controlled by wind in the higher free atmosphere and have turbulence due to interaction with surface features such as trees, hills, and buildings. Short term or high frequency variations are due to this turbulence in the boundary layer. Long term variations are due to the passage of transient waves in the atmosphere, with a characteristic time scale of several days.
The transient waves ar that influence wind in the Central U.S. are large scale and this results in the power output from wind farms in the region being correlated and not independent.

Sentence about the EU in lead paragraph[edit]

The article's lead paragraph includes the sentence:

"The EU wind industry has had an average annual growth of 15.6% over the last 17 years (1995-2011).[3]"

While an interesting fact, it is out of place in this article, especially in the lead. We are not told if the cited EU annual growth is larger or smaller than growth of wind power in the US over the same period. Unless this statistic is stated in the context of a comparison to growth of US wind power, I don't see the purpose of including it. Plazak (talk) 04:29, 18 February 2015 (UTC)

Agreed. In fact the whole lead section needs a lot of work. I'll try to get to it later this month if no one else manages to before then. --Aflafla1 (talk) 19:09, 7 March 2015 (UTC)

March 17, 2015 update[edit]

The update looks good except they took out the monthly generation data for 2002 and 2003 — Preceding unsigned comment added by Renewablejunkie (talkcontribs) 05:41, 31 March 2015 (UTC)

Removal of paragraph about U. of Utah report from lead[edit]

I had several problems with the paragraph as it was in this article. First it did not belong in the lead section. Instead the info should have been placed at the end of the Overview section where it would flow more naturally.

Secondly I don't like how the paragraph was worded. Instead, write a paragraph about the wind cost estimates being too high and use the report as the cite.

Thirdly, it has been widely discussed that this report was essentially funded by oil and gas industry interests. Professor Simmons' chair at the Utah university is funded by a Koch Brothers foundation.--Aflafla1 (talk) 03:01, 8 July 2015 (UTC)
