I&#x27;m uncertain how much solar panels will reduce emissions anyway... I mean it <i>could</i> encourage the use of more electric cars.  However, how much of SF&#x27;s electricity is generated from fossil fuels?  Beyond this, how much fossil fuel is expending bringing up the materials used in composition of the solar panels, not to mention shipping them to SF.<p>I would think that expanding BART, and&#x2F;or requiring impact fees on new construction to expand public transit, and&#x2F;or have walking distance access to grocery shopping would be a far greater impact.
