    a.  that's not what the study says.

    b.  did you read the diary?

    From the diary:

    The study is even conservative in its estimates.  For example, an efficiency rating of 13.5% was used for rooftop solar panels while a 20% efficiency rating is rapidly becoming the new normal with solar pv panels.  In five to ten years, a 25% efficiency rating will probably be the new normal, which means that rooftop solar pv alone could cover nearly half our current electricity needs.  In regards to urban utility scale solar, parking lots were excluded despite them having some of the greatest potential for urban solar power generation.  So, not only is the solar power potential likely even more than 100 times our current electricity generation, it seems clear that rooftop solar and urban utility solar alone could provide us with all our electricity needs.
