   “I don’t think it’s as much of a story of regulation as it is economic   
   efficiency,” said Jay Turner, professor of environmental science at   
   Wellesley College. “The price of batteries and renewable generation has   
   fallen so much that batteries and solar and wind, when put together, are   
   so cost-competitive.”   
      
   -------------------------------------------------   
   The battery depreciation cost per KWH discharged is a major factor. For   
   lead-acid it could be $0.20 or more per KWH, making "free" solar as   
   expensive as grid power. $100 / 500 = $0.20.  Lithium, especially LiFeP04   
   rated for thousands of cycles, promises storage costs in the range of $0.05   
   per KWH.

   $200 / 4000 = $0.05.
