All of them point to the same conclusions: 1. The volume of storage needed to convert intermittent renewable energy into dispatchable energy is very large, with estimates running in the 1 to 5.
With the rate at which renewable energy technology is advancing and cost effective renewable energy is becoming available, the United States needs to accelerate the transition from traditional energy sources to renewable energy sources.
