Energy storage

Definition

Energy storage refers to the capture of energy produced at one time for use at a later time. This concept is crucial in balancing energy supply and demand, particularly with the integration of renewable energy sources like solar and wind, which can be intermittent. By storing energy, systems can provide a consistent power supply and enhance overall energy efficiency.
