A microwave oven comprises a cooking cavity and a RF generation module configured to deliver microwave energy into the cooking cavity. A controller is operatively associated with the RF generation module. The controller receives and processes a signal indicative of current state of an associated energy supplying utility for determining whether to operate the microwave oven in one of a normal operating mode and an energy savings mode in response to the received signal. The controller is configured to at least temporarily block the signal when the RF generation module is activated if a frequency of the signal is at least partially degraded by a frequency of the RF generation module.

1. A microwave oven comprising: a cooking cavity;a RF generation module configured to deliver microwave energy into the cooking cavity; anda controller operatively associated with the RF generation module, the controller receiving and processing a signal indicative of current state of an associated energy supplying utility for determining whether to operate the microwave oven in one of a normal operating mode and an energy savings mode, wherein the controller is configured to automatically and without requiring user input, at least temporarily block the signal when the RF generation module is activated if a frequency of the signal is at least partially degraded by a frequency of the RF generation module;wherein the RF generation module operates on a duty cycle throughout a selected cooking cycle, the RF generation module cycling on and off during the duty cycle, the controller being configured to block signal communication during the entire duty cycle when the RF generation module is on. 2. The microwave oven of claim 1, wherein the controller is configured to selectively adjust and/or deactivate one or more power consuming features/functions of the microwave oven to reduce power consumption in the energy savings mode. 3. The microwave oven of claim 2, wherein the microwave oven further includes a fan, the controller being configured to reduce speed of the fan in the energy savings mode. 4. The microwave oven of claim 2, wherein the microwave oven further includes a light source, the controller being configured to reduce the intensity of the light source in the energy savings mode. 5. The microwave oven of claim 2, wherein the controller is configured to reduce a power level of the RF generation module in the energy savings mode. 6. The microwave oven of claim 2, further comprising a user interface operatively connected to the controller, the user interface including a selectable override option to enable a user to prevent the controller from selectively adjusting and/or deactivating the one or more power consuming features/functions in the energy savings mode. 7. The microwave oven of claim 2, wherein the user interface further includes a display communicating activation of the energy savings mode. 8. The microwave oven of claim 7, wherein the energy savings mode display includes a display selected from the group consisting of ‘“ECO”, “Eco”, “EP”, “ER”, “CP” “CPP” “DR”, and “PP”. 9. A microwave oven comprising: a cooking cavity;a RF generation module configured to deliver microwave energy into the cooking cavity; anda controller operatively associated with the RF generation module, the controller receiving and processing a signal indicative of current state of an associated energy supplying utility for determining whether to operate the microwave oven in one of a normal operating mode and an energy savings mode, wherein the controller is configured to automatically and without requiring user input, at least temporarily block the signal when the RF generation module is activated if a frequency of the signal is at least partially degraded by a frequency of the RF generation module;wherein the controller is configured to continue operation of the microwave oven in one of the normal operating mode and the energy savings mode during a time period that the signal is blocked; andwherein the controller is configured to queue the blocked signal during operation of the RF generation module. 10. A microwave oven control method, comprising: communicating with an associated utility;determining a state for an associated energy supplying utility, the utility state being indicative of at least a peak demand period or an off-peak demand period;operating the microwave oven in a normal mode during the off-peak demand period;operating the microwave oven in an energy savings mode during the peak demand period;automatically and without requiring user input, blocking the communication with the associated utility during operating of the microwave oven to prevent unreliable communications during operation of the microwave oven;queuing the communication with the associated utility during operating of the microwave oven; andprocessing the queue after operation of the microwave oven for at least partially determining current operating mode for the microwave oven. 11. The method of claim 10, further comprising selectively adjusting any number of one or more power consuming functions of the microwave oven to reduce power consumption of the microwave oven in the energy savings mode. 12. The method of claim 11, further comprising reducing power to a RF generation module of the microwave oven in the energy savings mode. 13. The method of claim 11, further comprising: reducing speed of a fan of the microwave oven in the energy savings mode, andreducing an intensity of a light source of the microwave oven in the energy savings mode. 14. A microwave oven comprising: a cooking cavity;a RF generation module configured to deliver microwave energy into the cooking cavity; anda controller operatively associated with the RF generation module, the controller configured to receive and process an energy signal from an associated utility, the signal having a first state indicative of a utility peak demand period and a second state indicative of a utility off-peak demand period, the controller operating the microwave oven in one of an energy savings mode and a normal operating mode based on the received signal being in the first and second states respectively;wherein the controller is configured to at least (i) reduce power of the RF generation module in the energy savings mode, (ii) determine a frequency of the incoming energy signal, and (iii) automatically and without requiring user input temporarily, block receipt of the energy signal when the RF generation module is activated if the determined frequency of the energy signal is impacted by a frequency of the RF generation module; andwherein the controller is configured to queue the energy signal during activation of the RF generation module and process the queue after deactivation of the RF generation module for at least partially determining current operating mode for the microwave oven. 15. The microwave of claim 14, wherein the microwave oven further includes a fan and a light source, the controller being configured to reduce at least one of the speed of the fan and the intensity of the light source in the energy savings mode.
