Biogas, generated during the decomposition of organic material managed in landfills, is used to generate electricity. One of the first to utilize biogas as a natural resource to produce renewable energy, the Sanitation Districts' energy recovery facilities at the Calabasas and Puente Hills Landfills provide reliable and economic electrical power to help serve Southern California's increasing energy needs.

Almost 79 megawatts (MW) of electricity is generated in Sanitation Districts' wastewater and solid waste operations. In total, the Sanitation Districts produce power equivalent to the needs of about 110,000 Southern California homes. Some of the electricity is used in powering Sanitation Districts' operations; the rest is used to reduce the amount of power produced by utilities, thereby, reducing greenhouse gas emissions.
