The social computing will integrate and enhance many digital systems over the next decade and the smart grid is no exception. Smart grid efficiency depends on utility customers having knowledge about demand response programs and being actively engaged in energy management. And this is exactly where social network comes into the picture and can really have an impact. Social computing can also expand the adoption and adaptation of smart grid technologies through the peer to peer communication in local communities through social network. It also could change large scale behavior through crowdshifting basing on the theory "people decide how to behave based on what they see others doing, especially if those others seem similar to themselves".
