Biofuel Oasis in Berkeley is an all-women worker-owned cooperative and urban resource for folks who want to lighten their ecological footprint and maybe raise a chicken or two. Besides selling biodiesel and farm supplies, the Oasis regularly offers workshops on diesel car maintenance; raising chickens, ducks and goats in urban environments; and rainwater harvesting and graywater for gardens, to name just a few.
Biofuel Oasis evolved from the Berkeley Biodiesel Collective, an offshoot of the Ecology Center. The collective was formed on Sept. 11, 2002, in response to the 9/11 tragedy. To help reduce gasoline consumption, the collective taught people to brew fuel from used vegetable oil.
