The flywheel material with the highest specific tensile strength will yield the highest energy storage per unit mass. This is one reason why carbon fiber is a material of interest. For a given design the stored energy is proportional to the hoop stress and the volume. [citation needed] An electric motor-powered flywheel is common in practice.
where m is the total mass of the flywheel rotor. Generally, the larger the energy density of a flywheel, the more the energy stored per unit mass. In other words, one can make full use of material to design a flywheel with high energy storage and low total mass. Eq. indicates that the energy density of a flywheel rotor is determined by the
