The Netherlands is working to achieve renewable energy efficiency with the recent installation of the world’s first solar bike path. 

In November 2014, Dutch physicists and engineers introduced the SolaRoad, a 70-meter bicycle lane that can generate solar energy. The lane is made with rows of technological blocks of solar panels, measuring 2.5 by 3.5 meters. Each solar panel consists of several solar cells. It is protected with concrete housing and a surface layer of hardened glass. The blocks are also slightly tilted to receive more sunlight exposure and to prevent gathering of dirt and water.

The SolaRoad was placed on a bike path between two suburbs near Amsterdam.  According to the developers, one of the reasons why this is an ideal testing location is that it is frequently used by cyclists. More importantly, the path is well-exposed to sunlight. Currently, the solar lane produces 30 percent less power compared to solar roofs. Despite this, it was able to produce 140,000 watts in its first 16 days.

The electricity produced by the SolaRoad currently goes to the national grid. However, the developers are hoping to enhance the solar lane as a power source for street and traffic-control lights, and electric transportations. It may also serve as power storage for emergency use in the future.

At present, the solar lane is still a pilot project. It will continue to operate for the next two years, during which the developers will study and explore its functionalities and limitations.
