Electric, hybrid, solar, and biofuel car owners showed off their ecofriendly wheels at Saturday’s Green Drive Expo in Richmond.

The annual convention, which was free for those who pre-registered online, attracted dozens to Craneway Pavilion, where speakers shared insight on the state of the green vehicle industry and its future.

Founder Eric Powers called Richmond a “hidden gem” for the show, adding that he believes it has helped the local economy by bringing automakers to the region.
