Pumped water storage renewable energy

Hydropower Basics | NREL

So-called pumped storage hydropower—also known as water batteries—can hold huge amounts of renewable energy for months at a time. This storage is very important. Solar energy and wind power only create electricity when the sun shines and winds blow, but water batteries can store excess energy that can be used at night or during gentle breezes.
