As the nation's largest natural gas utility, delivering affordable, reliable, and clean natural gas service to over 21 million customers, SoCalGas is a leader in researching and developing new technologies that improve energy efficiency, reduce emissions, and keep bills affordable for customers. That's why we're working hard to increase the production and use of renewable natural gas (RNG), or "biogas," derived from organic waste material. RNG is carbon neutral, fully compatible with existing pipeline infrastructure, and unlike wind and solar, is available 24 hours a day, 7 days a week.
