Lift-off: energy storage brings renewable energy to the mainstream
In the past, a severe shortcoming of renewables has been that they are intermittent: the power stays on only as long as the wind blows or the sun shines; if the wind blows too hard, the turbines must stop turning in order not to overload the grid. Newer and more efficient storage techniques are changing the equation. It is now possible to store excess power and tap into it during periods of power shortage. This article outlines some of the many technologies employed.
