Viewed from the window of a small Cessna airplane roughly 2,000 feet above the Earth, the lines of wind turbines like this one near Medicine Bow appear to crowd the landscape of Albany and Carbon counties.

While companies are slated to erect new wind turbines around the state, existing turbines are also becoming more powerful. PacifiCorp, the parent company of Rocky Mountain Power, is in the midst of its Energy Vision 2020 initiative, which involves both adding 1,150 megawatts of new wind power to its system and “repowering” older turbines with newer technology.  Those upgrades include replacing old turbine blades with longer, more productive designs. 

In this photograph taken on Aug. 9, blades rest on the ground next to turbines at what is likely a PacifiCorp owned wind farm. Though WyoFile was unable to precisely identify the facility, most turbines under the Cessna’s flight path were owned by PacifiCorp, according to an interactive federal database. It’s unclear whether the blades on the ground are recently-removed old blades or new blades waiting to be mounted. 

Wind’s gains will be coal’s losses — PacifiCorp is building transmission lines to plug its new wind-generated electricity into the regional grid, another step toward a future with less coal power in the nation’s energy mix.

WyoFile's goal is to provide readers with information and ideas that foster constructive conversations about the issues and opportunities our communities face. One small piece of how we do that is by offering a space below each story for readers to share perspectives, experiences and insights. For this to work, we need your help.

What we're looking for: 

  • Your real name — first and last. 
  • Direct responses to the article. Tell us how your experience relates to the story.
  • The truth. Share factual information that adds context to the reporting.
  • Thoughtful answers to questions raised by the reporting or other commenters.
  • Tips that could advance our reporting on the topic.
  • No more than three comments per story, including replies. 

What we block from our comments section, when we see it:

  • Pseudonyms. WyoFile stands behind everything we publish, and we expect commenters to do the same by using their real name.
  • Comments that are not directly relevant to the article. 
  • Demonstrably false claims, what-about-isms, references to debunked lines of rhetoric, professional political talking points or links to sites trafficking in misinformation.
  • Personal attacks, profanity, discriminatory language or threats.
  • Arguments with other commenters.

Other important things to know: 

  • Appearing in WyoFile’s comments section is a privilege, not a right or entitlement. 
  • We’re a small team and our first priority is reporting. Depending on what’s going on, comments may be moderated 24 to 48 hours from when they’re submitted — or even later. If you comment in the evening or on the weekend, please be patient. We’ll get to it when we’re back in the office.
  • We’re not interested in managing squeaky wheels, and even if we wanted to, we don't have time to address every single commenter’s grievance. 
  • Try as we might, we will make mistakes. We’ll fail to catch aliases, mistakenly allow folks to exceed the comment limit and occasionally miss false statements. If that’s going to upset you, it’s probably best to just stick with our journalism and avoid the comments section.
  • We don’t mediate disputes between commenters. If you have concerns about another commenter, please don’t bring them to us.

The bottom line:

If you repeatedly push the boundaries, make unreasonable demands, get caught lying or generally cause trouble, we will stop approving your comments — maybe forever. Such moderation decisions are not negotiable or subject to explanation. If civil and constructive conversation is not your goal, then our comments section is not for you.

  1. Hi Andrew,
    Hopefully, you are just scratching the surface of Wind Energy in Wyoming.

    If you want to get some good background on the Wind Energy issues and where the industry is headed read “Superpower” by WSJ Energy Reporter Russell Gold.
