A method for using excess energy generated by a renewable power generation system including at least one renewable power generator to treat organic waste material to generate crude oil. The method includes providing a renewable power generation management system operatively coupled to the renewable power generation system. The renewable power generation management system receives operational data from a pump load operatively coupled to the renewable power generator, and/or operational data from an electrical grid operatively coupled to the renewable power generator. Based at least in part on anticipated energy requirements, excess energy is supplied to the pump load to facilitate treating the organic waste material to generate crude oil.
