Question

What are examples of stored energy?

Answer 1

Hint: Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional and pumped. Grid energy storage may be a collection of methods used for energy storage on an outsized scale within an electric power grid.

Complete answer:
Stored energy ("potential energy") is everywhere:
A guitar string, because it is stretched while played, is actually a spring that stores elastic P.E. because the string is plucked, the energy is transformed into sound (pressure waves within the air).
The fuel in your car has chemical P.E. stored within the bounds of hydrogen and carbon. Once you tread on the accelerator, the fuel is burned within the engine and turns into fun and freedom (and kinetic energy).
Water behind a dam has gravitational P.E. because it's at a better elevation than the water downstream of the dam. This transforms into electricity because the water flows downward and pushes on giant turbines that generate power. (Sometimes in the dark, when power demand is low, otherwise-unused electrical power is employed to run pumps and push the water heater up behind the dam so it is often used during the daytime-basically an enormous gravity-powered battery).
The unburned hydrogen within the Sun has nuclear P.E. When fusion occurs, it transforms into, among other things, energy. Eight minutes later (the time it takes light to urge to earth from the Sun), you are feeling it as warmth on your face.

Note:
Energy storage is the capture of energy produced at just one occasion to be used at a later time to scale back imbalances between energy demand and energy production. A tool that stores energy is usually called an accumulator or battery.
