General Motors to Run Ohio, Indiana Factories With 100% Wind Power
By Greg Alvarez
Wind Powers the Open Road for GM
General Motors (GM) just announced wind power purchase agreements with projects in Ohio and Illinois. The automaker is buying enough wind-generated electricity to power the Ohio and Indiana factories that build the Chevrolet Cruze and Silverado, and the GMC Sierra.

"Technology is driving solutions for mobility and safety in our vehicles, as well as the new energy solutions that build them," said Gerald Johnson, GMNA vice president of manufacturing and labor. "This is the way we do business: offering vehicles that serve our customers' lifestyle needs while providing sustainable solutions that improve our communities."
GM already has plans to soon power 100 percent of its Arlington, Texas, plant using wind, where more than 100,000 SUV's are made every year. Wind's low cost, down 66 percent since 2009, has made it an attractive option for GM as it works toward meeting its 100 percent renewable goal.
Other Buyers Jump on the Bandwagon
GM isn't alone in the headlines this week. Kimberly-Clark, maker of products like Kleenex and Huggies, also announced a new wind deal in recent days. The company will soon source about 33 percent of its electricity needs from wind farms in Oklahoma and Texas.
"It's a powerful demonstration of sustainability initiatives having both great environmental and business benefits," said Lisa Morden, Kimberly-Clark's global head of sustainability.

Why Wind Power Makes Sense for the Fortune 500
Two recent reports looked at why companies like GM and Kimberly-Clark are pouncing on wind power.
David Gardiner and Associates examined the recent trend of manufacturers committing to buying renewables in a new report entitled "The Growing Demand for Renewable Energy among Major U.S. and Global Manufacturers."
David Gardiner and Associates surveyed 160 large U.S. manufacturers, finding that 40 currently have a renewable energy goal in place, and 18 of those 40 have 100 percent renewable targets.
The following 10 states host the most factories for those 18 companies: California, Texas, Ohio, Missouri, Illinois, Michigan, Oregon, Pennsylvania, Tennessee and North Carolina.
The report adds that manufacturers invest in renewable energy to lower energy costs, secure stable, low-risk energy prices and demonstrate corporate leadership. GM CEO Mary Barra confirms that "pursuit of renewable energy benefits our customers and communities through cleaner air while strengthening our business through lower and more stable energy costs."
Meanwhile, Greentech Media and Apex Clean Energy surveyed 153 large corporate buyers to see what motivates companies to invest in wind.
Eighty-four percent of respondents plan to actively pursue or consider directly buying renewables over the next five to 10 years, and 43 percent plan to be more aggressive in the next 24 months. Sixty-five percent report price as a leading factor in determining purchases.
So yet again, expect to hear more on this trend before long.
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
