If Boulder was big enough to qualify for the list of largest U.S. cities ranked for energy efficiency, it would knock Denver out of the top 10, coming in at No. 7. On the City Energy Scorecard, released in May by the American Council for Energy-Efficient Economy, Boulder outscored Denver by 10 points in building efficiency, earning a total of 69.25 out of 100. Denver came in 10th with 58.5 points.
Precision agriculture was originally enabled by GPS, allowing farmers to program GPS points into automatic seeders and sprayers so they could micromanage crops — but only after physically surveying the crops, which could take days or even weeks. Using drones, this work can be cut to a matter of hours.
Audrey Levatino is a self-sufficient farmer — she has to be since, she runs it singlehandedly. So when it came to using a chainsaw, she knew she had to overcome her trepidation. “I didn’t start using a chainsaw when I first started farming for three or four years because I was afraid of it. I always asked my husband to do it. But once you learn how, it’s easier than a lot of things women do every day,” Levatino says. “It’s intimidating because it always seems like it’s been in the realm of the man’s world, but it’s not. It’s just another tool.”
