Abstract
Energy systems, energy devices, energy utilization methods, and energy transfer methods are described. In one arrangement, energy utilization methods include providing first energy from a power grid to an induction generator at a first moment in time; using the induction generator and the first energy from the power grid, charging an energy storage device; using second energy from the energy storage device, powering a motor causing the induction generator to generate third energy during a second moment in time; and providing the third energy to the power grid. Other arrangements are described.
