Catalyzing California’s Clean Energy Revolution Through Renewable Natural Gas
California is setting a powerful example in its pursuit of a low-carbon future with the recent launch of a major renewable natural gas (RNG) facility at the Keller Canyon Landfill — the state’s largest landfill gas-to-RNG facility to date.
This collaboration between Ameresco, Republic Services, and Pacific Gas & Electric (PG&E) turns landfill waste into a sustainable replacement for fossil fuels, showing how transformative energy solutions can take root and grow across California and North America writ large. Today, Keller Canyon is converting up to 4,500 cubic feet of landfill gas per minute into around 1 billion cubic feet of RNG every year. Think about that. That’s preventing 62,000 metric tons of greenhouse gases from entering the atmosphere each year—the same as taking 30,000 cars off the road. And when we see the potential in projects like this, it becomes clear: this isn’t just about reducing waste. It’s about rethinking waste as a valuable resource that can help power the future we want to build, while reducing our reliance on fossil fuels.
