Making a Case for Flywheel Energy Storage
This is equal to about 500,000 kWh or 0.5 MWh of energy. Remember that this energy is consumed in less than two seconds, so to maintain a constant acceleration much of that energy will be consumed in the last half second. Even if we spread the energy evenly across the two seconds the power required approaches 1,000 MW.
