San Francisco company Otherlab has created a massive interactive “ Energy Literacy ” flowchart that shows all of the energy used in America. The company debuted the chart at an event run by Reinvent , a company dedicated to bringing innovators together to address the world’s most pressing problems. Pulling data from the Department of Energy and other sources, the diagram is the first of its kind to depict the complete flow of energy throughout the US economy. While this was a massive undertaking, perhaps it’s not so surprising considering the source. Otherlab is run by serial entrepreneur and MacArthur genius Saul Griffith, who once famously calculated the carbon footprint of every single action in his life . When he presented the chart, he told his audience, “I think we may be the first three or four people to read every footnote in every energy agency document ever produced.” The left side of the diagram shows where our energy comes from – the majority from coal , less than 1 percent from solar . By highlighting a section, readers can track a single energy source to its various ends, seeing just how much energy ends up wasted along the way. For example: with natural gas the waste is substantial, with only half of the generated energy being used. Related: Americans used less energy in 2015, but more wind, solar, and geothermal power Some of the major uses of our energy should come as no surprise, such as that used for basic infrastructure. Other uses, like the energy used by US military jets, may raise questions readers didn’t even realize they had. By charting out the connections between all of these industries and our energy production, Griffith hopes it will be possible to better understand the economy and for policy decisions to be made with more accurate information. + Energy Literacy Via Co.Exist Images via Energy Literacy and Kevin Dooley

Researchers find that LED light makes milk taste bad

Milk that has been sitting under LED lightbulbs does not do the taste buds good, new research finds. Cornell University taste tests revealed that consumers find two week old milk shielded from the light preferable to fresh milk exposed to LED light for as little as four hours. As grocery stores are turning to more efficient lighting, this creates a problem for dairy industries. “For some reason we love to look across the store and see this glowing case of milk that’s shining bright,” said Robin Dando, assistant professor at Cornell University’s Department of Food Science and senior author of the study. “It’s attractive to look at, but we might actually be damaging the quality of the product.” Exposure to sunlight and artificial light sources is known to affect the quality and taste of milk. LED’s unique effects could be causing problems as grocers switch to more energy-saving lighting methods. Related: New pea-based milk uses 93 percent less water than dairy equivalent LED lighting typically emits in the blue spectrum and influences how the nutrient riboflavin absorbs light. Riboflavin, as well as other photosensitive components, degrades the proteins in milk and oxidizes the fats, leading to a taste some describe as similar to cardboard or plastic . Cornell’s study revealed that customers were turned off by fresh milk exposed to LED light for as little as four hours, as compared to milk up to two weeks old that had been hidden from LED effects. Nicole Martin, lead author of the study and supervisor of the Milk Quality Improvement Program laboratory at Cornell said, “This study shows that light exposure is a much greater factor explaining deteriorating milk quality than even age.” Via  Morning Ag Clips Images via Flickr ( 1 , 2 )
