Grid energy storage

Grid energy storage is a way to store electricity when it is not being used. It works like a battery: electricity is put in when not being used, and then taken out when it is needed. This is helpful because electricity can be used even when there is no electricity being made, like on a cloudy day or in the middle of the night. Grid energy storage makes sure that we always have enough electricity to do the things we need it to do.
