California’s largest energy utilities are planning a new round of power cuts that will bring blackouts to hundreds of thousands of homes and businesses over the next two days. Pacific Gas & Electric says dry and windy conditions are forcing it to cut power to more than a half-million people in Northern California in order to prevent a repeat of last year’s devastating Camp Fire, which killed 85 people after poorly maintained PG&E transmission lines sparked the blaze. Meanwhile, Southern California Edison and San Diego Gas & Electric are planning to shut off power to more than 300,000 customers, after a fire in the western Los Angeles neighborhood of Pacific Palisades damaged multimillion-dollar hillside homes. Climate scientists say greenhouse gas emissions are making California hotter and drier, leading to bigger and more frequent fires.
