Each event presents speakers and topics discussing the most important environmental issues of our time. All are welcome, Sierra Club members as well as nonmembers.

For Green Friday on January 11 there will be a presentation on the East Bay Municipal Utility District’s (EBMUD) Wastewater Energy Production Program. The presenter will be EBMUD’S John Hake, Supervisor of Wastewater Energy Production. EBMUDs wastewater treatment plant is more than a treatment plant, it’s a green factory. Biodegradable wastes in sewage, food scraps, and grease from local restaurants, plus waste streams from wineries and poultry farms are mixed together in large tanks and digested by microorganisms. The biogas emitted by the microorganisms is captured and used to generate renewable energy to power the wastewater treatment¬†plant.¬† In¬†2012, EBMUD became the first wastewater treatment plant in North America to produce more renewable energy onsite than is needed to run the facility. This monumental accomplishment was made possible when EBMUD installed an energy-efficient, low-emission gas turbine in 2011. The District sells excess renewable energy back to the electrical grid to cut fossil fuel use and greenhouse gas emissions, and provide savings for EBMUD ratepayers. Biogas production saves EBMUD approximately $3 million each year by reducing electric power demand.
