“I can’t overemphasize the calamity that these events cause at the neighborhood level. Hundreds of health care facilities don’t have back-up generators,” said Jack Brouwer, an engineering professor and director of the National Fuel Cell Research Center at the University of California, Irvine. Referencing the deaths caused by previous wildfires in California, he said, “If you’re out of power for an hour, that’s fine, but for a couple of days — those lives count as much as those that would be lost in a fire.”
