Can You Store Electricity for Later?
A flywheel is a mechanical device. It rotates and stores energy. First, electrical energy is used to make it spin. The spinning creates kinetic energy. Then the electrical energy gets turned off. But because of inertia, the flywheel will keep spinning. Later, you can turn the kinetic energy back into electrical energy.
