What does wind and solar storage mean

A wind and solar energy storage system is a mechanism that captures electrical energy generated by wind turbines and solar panels for later use. 1, The primary purpose of such systems is to balance energy supply and demand, **2, thereby ensuring a continuous and reliable power output, **3, These storage systems incorporate technologies such as batteries, pumped hydroelectric systems, or compressed air energy storage to hold surplus energy produced during peak generation periods and release it during times of high demand or low production, **4, This capability is crucial for integrating renewable energy sources into the grid as it mitigates the intermittency associated with both wind and solar power, thereby enhancing the overall reliability and efficiency of energy systems.
