As the flywheel spins faster, it experiences greater force and thus stores more energy. Flywheels are thus showing immense promise in the field of energy storage systems designed to replace the typical lead-acid batteries. For a flywheel, kinetic energy is calculated as for a spinning object, as
Energy is discharged by drawing down kinetic energy using the same motor as a generator. But it is not a primary source of power generation. Extra power in the grid is shunted to the flywheel and used to set them in motion. When the power is required later, the momentum of the flywheel is used to generate power fed back to the grid.
Flywheels are often large and heavy because they are able to store more energy that way. On the other hand, smaller and lighter wheels are also used in many situations because they can spin much faster and thus much more kinetic energy is generated this way. Thus there are different sizes and shapes of flywheel.
