Holding up the rear is Inyo (6%), Glenn (5.5%), and Lassen (5.4%), which makes sense (EVs likely don't meet needs well in those counties yet). And finally, Modoc (0%), where one brave soul registered a Chevy Bolt EV, the only ZEV sale in that county in all of 2023.

Southern California is playing catch-up, with Orange County at 32% followed by San Diego (28%), Ventura (26%), Los Angeles (26%), Santa Barbara (21%) and Riverside (20%), matching more rural counties like Yolo (25%), Placer (26%), and Sonoma (26%).
