Stored Hydro Electric Power stations can save our environment, our energy and our future too. Here is a link to the Wiki article regarding stored hydro electric energy systems.
Many countries arround the world are using energy storage systems. There are several different types of systems to store energy. Most of these systems are Dams holding back water from a river or snow melt. Some are designed and built just for the purpose of storing extra energy that we dont need. These systems are used to store the energy untill it is needed. The water flows down hill and drives generators like in a regular dam. The difference with stored-hydro-electric is that it is designed to push water up hill when there is an excess ammount of energy.
