It turns out that the pursuit of energy efficiency isn’t just some newfangled political fad thought up by climate scientists and mechanical engineers… it’s in our genes! According to a team of researchers at the University of Arizona, humans learned to walk upright because doing so uses less energy than traveling on all fours. This is a fun fact, all by itself, but I can’t help thinking… maybe pursuing an energy efficiency revolution is the next phase of human evolution?
