Wind turbines are a net positive for a sustainable society, but that doesn’t mean they don’t have an environmental impact. Apart from their material requirements, those giant, spinning blades can be lethal to unsuspecting winged animals like birds and bats . Although some reports dramatically overplay wind farms’ danger to flying species, there is no denying they can unintentionally kill anywhere from two-to-six birds and four-to-seven bats per megawatt every year. That may not seem like many fatalities, but every animal counts for an endangered species. To lower these risks, engineers are devising new ways to make wind turbines more visible and avoidable. One potential solution may involve taking a cue from some of nature’s most dangerous creatures.…
