<human>: I've been hearing a lot about the'smart grid' and I'd like to know what it is and why it's important.
<bot>: The smart grid is an electrical grid that uses digital technology to control the flow of electricity. It’s designed to make our power system more efficient, reliable, and secure. Smart grids use information from sensors in homes, businesses, and other buildings to help manage energy usage and deliver electricity when and where it’s needed. This helps reduce energy waste and makes our power system more reliable.
