California’s busy freeways could soon be helping to provide clean energy.

The California Energy Commission (CES) has approved grant funding for two piezoelectric-based systems. Piezoelectricity is a renewable energy generated via mechanical stress. This means the vibrating movement of vehicles could be the ideal catalyst to produce it.

CES said it will back two projects to promote piezoelectricity. “The University of California, Merced and PYRO-E, LLC will receive grants to demonstrate electrical harvesting systems built into roads,” CES confirmed.

Here’s Akshat Kothari – from Dubai International Academy – explaining piezoelectricity in 2015.
