The apparatus is comprised of a first wind receiving member displaceable by a wind having a variable velocity, a first elastic member coupled to the first wind receiving member, and an electrical generator operatively connected to the first wind receiving member and configured to convert mechanical energy of the first wind receiving member to electrical energy. An energy storage device may be provided in communication with the electrical generator. A self-powered signal communications system including the apparatus is also disclosed. A method of identifying a site for recovering variational wind energy is also disclosed.
