A business methodology for optimizing energy procurement energy demand (usage) and energy supply for a facility or complex. After ascertaining a baseline model, energy consumption is monitored and adjusted to reflect dynamic economic factors of operations. With the accumulation of data, contract negotiations with energy suppliers may provide further energy savings. Over time and patterns of usage determined further savings and optimization in energy, equipment, staffing and other operational areas are obtained. Remote access provides efficient monitoring of established systems.

Systems and methods for providing energy management utilize wireless wide-area network broadcast signals and a decentralized receiver architecture to allow customers to make informed choices with regard to energy consumption and load shedding for particular appliances. A receiver assembly embedded within an appliance receives a broadcast signal, e.g., an FM subcarrier signal, including tariff data and other electrical grid data. A processor coupled with the receiver controls the appliance in accordance with the received data and in accordance with user-defined preferences. In some embodiments, a transceiver assembly is embedded in one or more appliances in a household. Each transceiver is configured to receive broadcast signals regarding grid data, and to communicate with other appliances and/or a usage meter over a wireless personal area network. Meter data from one or more households may be aggregated and uplinked back to the energy provider or other entities.

A decentralized load management and control system and method are provided herein. A plurality of loads in a system are associated with a multitude of respective networked load controllers. If energy demand exceeds optimum limits in operation then the networked load controllers collaborate to determine which load(s) will be shed based on an optimization algorithm that considers, inter alia, variable load priority and business objectives. Additionally and/or alternatively, if the metered energy demand is less than optimum, the load controllers can determine which loads to reconnect again based at least upon load priority and business objectives.

A method and system are provided for auditing, monitoring and controlling the energy consumption within a utility. Energy consumption data is obtained from a series of modules monitoring and controlling a variety of physical conditions, such as ambient light, temperature, pressure, air velocity, cooling, and heating, and devices. These modules transmit energy consumption and physical conditions data over a wireless personal area network (WPAN) through a transceiver. A central control station obtains the energy consumption data and stores it in an energy usage database. Energy management logic calculates and provides to the user an energy management solution, to reduce energy consumption and costs, by applying rule-based artificial intelligence to the stored energy consumption data in conjunction with information from the Internet. In one embodiment, the energy management solution can automatically control devices to effectively conserve energy.

An energy management method for controlling electric vehicle charging by managing plural local energy sources, to optimize charging speed and minimize energy cost.

The method, terminal and computer program product determine the acceleration of a mobile terminal associated with the short-range communication transceiver and adjusts the power consumption of the short-range communication transceiver based upon whether a predefined acceleration threshold has been exceeded. To adjust the power consumption, the frequency at which the transceiver is activated may be altered. Thus, the power consumption of the transceiver may be reduced when the acceleration threshold is exceeded and/or may be increased when the acceleration threshold is not exceeded. Due to the adjustment of power consumption by transceivers, power is conserved in the mobile terminals associated with transceivers, which permits the mobile terminals and the transceivers to operate longer without requiring charging or replacement of the power supply.

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. Prices are set by comparing the cumulative actual and desired demand

The method, terminal and computer program product of the present invention are capable of adjusting the power consumption of short-range communication transceivers, such as RFID, IR transceivers or the like. Energy management of the transceiver is achieved by limiting activation of the transceiver to periods of user-interface illumination. The transceiver, therefore, uses less power because it is only activated by an intentional gesture by the user, i.e., a gesture that will initiate the illumination of a user-interface. In addition, the user of terminal is aware, via observation of the illumination, that the terminal is in an active transceiver reading state and, thus, the invention provides for a safe environment in which inadvertent reading of tags or data communication is lessened.

The connections between the grouped mesh networks can be passive using directional antennas or passive antennas or active using higher power RF devices, solar repeaters, mobile mesh devices, etc. The energy data is routed in a smart manner, by performing load balancing at gateways, by monitoring the signal to noise ratio of available communication paths, etc. Mesh clusters can also be created to define low power clusters, address blocking clusters, and frequency based clusters. Grouping clusters facilitates the efficient transfer of energy data from an energy sensing device to a energy management station.

The methods, apparatus, systems and computer program products provide for sensing a magnetic field, emitted by a short-range communication source, to activate short-range communication modules in a mobile terminal.

As such, the invention reduces the overall power consumption of the terminal by limiting the active state of the short-range communication module. By conserving power the mobile terminal is capable of operating for longer periods of time without requiring charging or replacement of the power supply.
