The 5,875 square metres of highway in Jinan runs for one kilometre or enough to meet the energy demands of about 800 homes, including two lanes and an emergency strip. The ground-breaking highway is made up of three layers:
Transparent concrete on top
Photovoltaic solar panels in the middle
If the technology proves effective, the electricity generated by the panels could power everything from street lights to signboards, and even a snow-melting system on the road. Excess energy can get sent to state grid.
China's road costs about $458 per square meter, which is much more expensive than, say, traditional asphalt.
Still, this project showcases China's multibillion dollar plow into renewable energy. By 2020, the country is aiming to build 54.5GW of large-scale solar projects.
