Simultaneously, it may also produce and store energy, such as electricity or hydrogen, that can be used to fuel vehicles, provide a means for independent production of household energy needs, or both. Various factors, such as the production of thermal energy and electricity from the renewable sources, the current store of stored energy, the current and expected thermal and electricity requirements of the building (based on a profile), the current and expected electricity loads of the equipment used to process stored energy, the expected thermal and electricity generating capacity of the renewable sources and other factors can be used to determine the mix of renewable-based and utility-based energy that minimizes the total energy cost. | 2009-02-19 |

20090048718 | Multi-building control for demand response power usage control - An energy usage coordinator controls the energy usage of individual buildings of a group (or portfolio) of buildings in one or more load zones.

Such a preferential rate may be in the form of a fixed rate reduction or a variable rate reduction. Alternatively, the energy company may determine that the energy is currently selling for twice what its building portfolio has contracted to pay for it so it requests some portion of the portfolio to reduce usage so that it can sell the excess/saved energy in the market. | 2009-02-19 |
