1. A method for storing energy in earth materials comprising:
storing elastic potential energy in the earth materials by applying a compression force on the earth materials, wherein applying the compression force on the earth materials comprises:
applying a tensile force to a tensile member by a motor-generator, wherein the tensile member is coupled to the motor-generator at a first end of the tensile member, and wherein the tensile member is coupled to an anchor at a second end of the tensile member;
storing the elastic potential energy in the earth materials for a period of time without substantially receiving electrical power at the motor-generator and without substantially generating electrical power by the motor-generator; and
generating, by the motor-generator at a time after the period of time, electrical power by releasing the stored potential energy, wherein releasing the stored potential energy comprises reducing the compression force on the earth materials, and wherein reducing the compression force on the earth materials comprises reducing the tensile force applied to the tensile member by the motor-generator.
