4. The electrical device of claim 1 in which the processor further executes the instructions to:

instruct each of the home appliances a specific time to commence operation based on the time in the consolidated future time range that was received from the electric utility, wherein the specific time occurs on or after the time received from the electric utility.

5. The electrical device of claim 1 in which the processor further executes the instructions to:

analyze historical data to predict an amount of power that solar panels will generate during the consolidated future time range;

reduce the consolidated amount of power by the amount of power that the solar panels will generate during the consolidated future time range; and

transmit the consolidated amount of power to the electric utility after reducing the consolidated amount of power by the amount of power that the solar panels will generate during the consolidated future time range.

6. The electrical device of claim 1 in which the processor further executes the instructions to:

transmit the consolidated amount of power and the consolidated future time range to several different electric utilities;

request, from the several different electric utilities, price quotes to purchase the consolidated amount of power during the consolidated future time range; and

analyze the price quotes to select one of the several different electric utilities that offers a lowest price for the consolidated amount of power during the consolidated future time range.

7. The electrical device of claim 1 in which the processor further executes the instructions to:

analyze forecasts of weather to determine whether a temperature will fall or rise; and

pre-purchase power for the home appliances from the electric utility when a determination is made that the weather will fall or rise.

8. A method executed by a processor in an electrical device to reduce a cost of electricity to a customer and to reduce peak demand to an electric utility, the method comprising:

determining, by the processor and for appliances of the customer, amounts of power to be used by the appliances during future time ranges that extend for greater than a time needed for the appliances to use the amounts of power;

consolidating, by the processor, the amounts of power into a consolidated amount of power;

consolidating, by the processor, the future time ranges into a consolidated future time range;

transmitting, from the electrical device, the consolidated amount of power and the consolidated future time range to the electric utility;

receiving, at the electrical device and from the electric utility, a time during the consolidated future time range when the appliances of the customer can begin to use the consolidated amount of power; and

instructing, from the electrical device, the appliances when in time operate such that the appliances commence usage of the consolidated amount of power at the time received from the electric utility.

9. The method of claim 8 further comprising:

monitoring, by the electrical device, weather forecasts that predict changes in temperature during a future time; and

communicating, by the electrical device, with the electric utility to pre-purchase power for use by the appliances during the future time in order to purchase the power at a lower cost.

10. The method of claim 8 further comprising:

communicating, by the electrical device, with other electrical devices of other customers to form a group that is formed of the customer and the other customers;
