France plans on pulling its weight post-Paris climate talks, at which 195 nations made a commitment toward building a zero-emission economy. The country has started by laying down 621 miles of solar panels to supply 5 million people across France with renewable energy.
Other countries have been testing the idea of solar roadways through solar bike paths. These small-scale projects operate as a pilot program to see if installing photovoltaic cells would be profitable on larger roads. These real-world trials examine potential losses in solar absorption from blockage from pollution, passing cyclists and pedestrians, and weather.
