Abstract: A computer-implemented system for consumers and suppliers of energy provides an on-line marketplace where energy consumers may learn about their options for obtaining energy and enter contracts with energy suppliers. Energy suppliers may use the system to learn about other suppliers as well as consumers, and to extend offers to consumers for the provision of energy. The system gathers data on suppliers and consumers from numerous reliable sources, and thus provides a content-rich environment that facilitates consumer choice in the selection of energy suppliers.
