Pumped Hydro
Pumped Hydro, also known as pumped storage hydropower, is a way to store large amounts of energy using water and gravity. Think of it like a natural battery - when power is cheap (like during off-peak hours), water is pumped uphill to a storage reservoir. When more electricity is needed, the water flows back down through turbines to generate power, similar to a regular dam. It's one of the oldest and most reliable ways to store energy for the power grid, especially important now with the growth of solar and wind power which don't generate electricity consistently.
