It’s good to know that wind turbine blades are a bird’s best friend, or something like that. I’m citing “fun facts” on the website of Synergy, Western Australia’s state-owned electricity generator. Synergy operations include half a dozen WA wind farms, mostly coastal. Synergy claims, correctly, that its fun facts “may blow your mind.” Fun Fact No. 9 is illustrated with a pic of Sesame Street’s Big Bird, pop-eyed with delight about wind turbines’  blade-and-splatter prospects. The caption reads (author’s emphasis)

Wind technology is now much more bird-friendly. Earlier versions of wind farms, such as the ones first launched in the US, had thousands of small fast-spinning turbines. Not so good for birds. Now, wind farms have taller and slower-moving blades which are much nicer for our feathered friends.

I don’t know about those “slower moving blades”. Tip speed of a 75m blade for a giant 6MW turbine can be 290km per hour. Despite my blown mind, I also…
