We all know producing electricity is an energy-intensive process, but the complications don't stop at how utilities generate that power. Demand for electricity ebbs and flows, and often doesn't correlate with generating capacity. One way of dealing with these fluctuations in supply and demand is to store energy for later use--and according to Navigant Research, it's an area in which California utilities are taking a lead. Energy storage involves converting electricity into some form of stored energy, then converting it back when it's needed to meet high demand. By doing so, you can both...
