As part-night lighting (i.e., turning off streetlights in the middle of the night) becomes more widespread among local authorities, three studies focusing, respectively, on robins, toads and bats show that, often, turning off the lights for a few hours is not enough to restore natural night. In terms of biodiversity, the challenge is not just about switching off the lights, but knowing when and where to do so.
In recent years, switching off street lighting in the middle of the night has turned out to be a no-brainer for several challenges: reducing energy bills, demonstrating a commitment to energy efficiency, and limiting light pollution and its effects on ecosystems.
