One way of thinking about energy storage is traditional fossil fuels, with a whole speculator's oil market attached to it. There is another way of thinking. When one barely have a shortage of something, like spring water, which flows from mountains (and fluctuates heavily depending on season, monsoon, etc) one probable doesn't store much and let it flow. For wind and solar, it seems, this is much better paradigm. Send it to the grid when its available, get it from the grid when it is still and cloudy.
