<human>: I've been hearing about the new "smart meters." What are they and how do they work?
<bot>: Smart meters are electronic devices that measure the amount of electricity being used in your home. They typically have a display screen that shows you how much energy you're using at any given moment, as well as an interface for setting up alerts if your usage gets too high or low. The technology is designed to help you monitor your energy use more easily and save money on your electricity bill by reducing unnecessary consumption.
