Temperatures in many California cities are cooling down this week, but a debate is simmering on how to generate enough electricity to power the state through extreme weather events while transitioning away from a reliance on fossil fuels. The California Energy Commission voted Wednesday to extend the life of three gas power plants along the state's southern coast through 2026, postponing a shutoff deadline previously set for the end of this year. The vote would keep the decades-old facilities — Ormond Beach Generating Station, AES Alamitos and AES Huntington Beach — open so they can run during emergencies.
