Comment on Elements of Renewable Energy
rtxn@lemmy.world 1 week agoYou can’t turn other forms of energy into solar or wind and store it in those forms. In contrast, hydroelectricity can store energy in pumped storage systems where excess electricity is used to move water to higher elevation (exchanging electricity for potential energy).

yes, and more importantly, normal Hydro plants could be updated to release water at selected times, to create “on-demand power”. The energy is stored in the water behind the dam. So conventional, already-existing hydro dams can perform a two-sided function: Storing water, and to release it on-demand. Like a battery that is refilled by nature.

AFAIK, that’s exactly what storage power plants do …wikipedia.org/…/Pumped-storage_hydroelectricity
