They make it sound like this is a problem only with renewable energy, 
when, in fact, it is a concern with all types of power generation.  The 
down time for solar generators is at most a few day, and usually just a 
few hours.  A nuclear plant is generally down for months to refuel.  And 
storage requirements go up based on time required.  Pump storage is 
reasonable proposition, I think.  The bugaboos are where you get the 
water and where you put it.  A mine and a slag mountain, and captured 
water, sound like reasonable choices to me, but I don't know any details.

Thank You Kindly,

Corwyn
