A renewable electric power system includes a high temperature superconducting wind turbine using high temperature superconducting yttrium-barium-copper oxide for the rotor and stator windings as well as a superconducting bearing. Power from the turbine is stored in a high temperature superconducting magnetic storage system that also uses HTS YBCO. Also included is a regenerative solid oxide fuel cell/electrolyzer with steam turbine cogeneration. The system operates on a managed day/night cycle. During daytime, the energy produced by the wind turbines and fuel cells is transmitted to the grid. During nocturnal hours, the wind turbine is used to provide low cost electricity to the reversible fuel cells operating in the electrolysis mode producing hydrogen and oxygen that is stored for later use. Alternatively, the fuel cells can remain in electrolysis mode producing hydrogen and oxygen for the market. A modified interactive system generates power on a continuous twenty-four hour cycle.
