Geo Quiz

City in southern France

We’re turning down the lights in Geo Quiz. We’re looking for a city on the banks of the Garonne River. The Garonne flows across northern Spain and southwest France before spilling into the Atlantic. This conservation-minded city has thousands of free bicycles to promote car-free commuting.

Now it’s just installed some new streetlights along the river. The prototype lights brighten up when pedestrians go by, they’re triggered by human body heat. They automatically dim when no one’s around. The city hopes the streetlights will cut energy consumption by as much as 50%. So can you name this city whose river walkways light up as pedestrians pass by?
