In his first month in office, Mayor Ed Lee assembled a team of energy experts to help San Francisco meet its ambitious goal of having all electricity in the city come from renewable sources by the end of 2020.
But over the past year, Lee has overseen the evisceration of a renewable power program that clean-energy advocates, analysts and that task force say is critical to San Francisco meeting its goal.

The mayor says his opposition centers on details of the proposed program. But critics, including some former high-level city officials, blame the mayor’s position on an extraordinarily close relationship with Pacific Gas and Electric Co.
