The role of energy density for grid-scale batteries

Because the sun does not shine at night but all our screens do, we need energy storage to shift solar energy production during the day to when it is needed in the evening. To cope with this intermittence of renewables, we cannot rely on wind production, which is not constant either; therefore, thousands of shipping-container-sized lithium-ion batteries have been installed in power grids around the world.
