For the cost of these solar panels, what else could we be doing to reduce carbon emissions?  Here in SF or internationally?<p>I do think that carbon reduction is pretty essential, but it&#x27;s so essential that I don&#x27;t think we can waste our money on low yield actions.  I&#x27;m not saying this strictly is, I&#x27;d have to read about it more, but I&#x27;m not optimistic that mandating very specific technologies will be a good approach.
