Tobias Trübenbacher, a Berlin-based designer and student at the University of the Arts Berlin, has one such solution. Trübenbacher has created a street light called Papilio that combats energy pollution on two fronts: it’s wind-powered, which reduces its dependence on electricity, and the light itself has a motion sensor that’s only activated when someone passes underneath it…

Trübenbacher designed Papilio in response to these global problems, saying that he initially chose to create a city-facing streetlight because of such lights’ role in light pollution. The lamp is shaped like a pinwheel that acts as a wind turbine, catching the wind to produce its own energy, which makes it climate-neutral. It also has a rechargeable battery that stores electricity, so the lamp can operate even on less windy days.
