Abstract: A hybrid energy market and currency system is provided to manage energy consumption in an energy market comprising a community of users. A central energy authority issues energy currency units to users and sets an exchange rate between the energy currency units and a monetary currency unit, thereby setting a variable price for energy. Energy currency units have a defined validity period at the end of which the energy currency unit is automatically converted to monetary currency units by the central energy authority. Users consume energy currency units through use of energy consumptive services, such as domestic consumption of electricity and water, and through use of transportation. Users are also able to buy additional energy currency units from the central energy authority, and to sell them back. Users cannot speculatively trade energy currency units.
