California's nearly 2 million cows, most living on industrial-scale dairies, create a huge and costly waste problem. According to the PUC order approving the BioEnergy deal, a single thousand-pound dairy cow each day produces 10 pounds of "volatile solids" - that's bureaucratese for poop - which can be transformed into 72 cubic feet of biogas. Dairy owners can dispose of that burden, clean up the environment and turn crap into cash by cutting deals with companies like BioEnergy. PG&E benefits as the biogas produced counts toward a state mandate that it obtain 20 percent of its electricity from renewable sources b y 2010. Such projects typically produce some sort of green "credits" that can be used toward meeting emissions limits or can be sold on carbon trading markets. PG&E will retain some of those so-called environmental attributes produced by the cow power project though the PUC said it remains to be decided just how they might be applied when California's cap on greenhouse gas limits comes into force.
