` :An August 2005 press release (here) says, ``The utility currently supplies 31 percent of its customer load from renewable resources—18 percent from its large hydroelectric facilities and 13 percent from small hydro and other renewable resources that qualify under California’s RPS Program—one of the highest volumes of any utility in the United States.``  So hydro is 18+13=31% of the 31% of renewables.  The axe they seem to have been grinding is that despite providing power to Berkeley and Marin and other bastions of altruism and virtue, PG&E; has virually nothing in the way of production from solar, wind, tide, or whatever else, if you take away the admittedly impressive amount of hydro.  — `
