"A few dozen protesters brought a charged jolt to a morning panel at the DTECH energy conference in San Diego yesterday, climbing onto the stage and chasing PG&E's vice president for wildfire mitigation away from the podium. Activists packed the front of the room with blue signs and loud chants, forcing panelists to step down while the moderator urged the audience to clear out. The disruption halted a session billed as a discussion of technologies for locating and identifying wildfires."
