The first aptly-titled SolaRoad made its debut last November in the Netherlands, not far from Amsterdam. The road itself is a unique foray in pollution-free solar energy. Nearly one year later, the SolaRoad’s designers say the high-tech bike path is performing better than they expected.In the first six months since it was installed, the SolaRoad has generated over 3,000 kilowatt-hours — or roughly the equivalent required for a single-person household for one calendar year.
