California is the largest dairy state in the United States, with approximately 1.8 million cows. California’s dairy cows produce enough waste to generate 550 megawatts of renewable electricity or more than 100 million gallons per year of carbon negative transportation fuels. Biomethane generated from dairy waste is the lowest carbon fuel of any in existence, more than 300 percent lower greenhouse gas emissions than gasoline or diesel. Dairy waste can also be used to generate flexible generation renewable power, which is critical to complement wind and solar power because it’s available 24/7 and can be stored for short periods of time to be used as needed. In addition to cutting methane emissions and producing renewable energy, converting dairy waste to energy reduces air and water pollution from dairies, cuts odors, and can provide revenue and onsite energy supplies to dairy farms.
