In a small northern town in France a road has opened which is paved with solar cells. The goal is to see if the highway can power the town, which has 3,400 residents. On the other hand, it still wasn’t cheap for them to build it. In order to fashion a single 1 kilometer lane it cost around 5 million euro. It is also not the most energy efficient way to harness solar energy because the panels are flat on the ground and not optimally oriented towards the sun throughout the day. Nevertheless, it is a way to generate clean energy from existing infrastructure. Its been said that the government hopes to expand the project to other roadways as well.
With advent of more effective solar cells we may see the price drop per kilometer of pavement bit by bit!
