One of the biggest challenges confronting the move toward a cleaner, more efficient electrical grid in the U.S. is that all of the devices, meters, wireless networks and software platforms created by an endless array of companies need to be able to communicate seamlessly with one another. This list is the first major attempt by the government to make sure this happens fast.

Once this smart grid is in place, then complete control over various segment populations can be achieved with the flip of a switch. Further, each device on the smart grid will have a unique identification number that will be logged each time the device is used on the grid. Processing the log will allow anyone to determine when these devices were used.
For example, once the smart grid is in place, a household's usage of electricity and appliance will be able to be monitored and itemized to a very specific detail. The grid will be able to tell that you used your microwave oven for four (4) minutes at 6:45pm based on your home's power draw at that time. This information would then be analyzed, resulting in the the conclusion that Brand X microwave oven has this same unique power draw. Now the grid knows you own a Brand X microwave oven. However, if this Brand X microwave has been recalled or is no longer legal, then the grid will not power this appliance. It will simply shut the electricity off to the Brand X microwave. Instead it will notify you that the appliance is not compliant and what your penalty will be.
