When a massive fire erupted at one of the world's largest lithium-ion battery storage facilities in Monterey County, it didn't just send a toxic plume of smoke over nearby communities — it cast a shadow of doubt over the future of California's clean energy industry.

The Monterey County Board of Supervisors declared a state of emergency following the massive blaze that has residents and officials concerned.

The blaze broke out late Thursday at the Monterey County plant that stores and sells power to Pacific Gas & Electric.

Over the last week, firefighters have fought some of the largest wildfires in Los Angeles, burning down hundreds of homes – and businesses, like one of the largest battery plants in Northern California.
