One of the primary disadvantages of flywheels is their weight. Flywheels are typically made of heavy materials such as steel or cast iron, which can make them difficult to handle and transport. The weight of the flywheel can also impact the overall efficiency of the system, as it requires more energy to get the flywheel spinning initially

Flywheel Energy Storage. Flywheel energy storage works on the principle that when power is abundant, the flywheel is driven by electric energy to rotate at a high speed, converting the electric energy into mechanical energy for storage; when the system needs it, the flywheel decelerates, and the motor acts as a generator to convert
