A smart grid is an advanced electrical grid that uses digital technology to monitor and manage the flow of electricity. It enhances the reliability and efficiency of power distribution by integrating various technologies, such as sensors and smart meters, which provide real-time data on energy usage. This allows for better management of energy resources and helps reduce outages. Smart grids also support the integration of renewable energy sources, like solar panels and wind turbines, into the power supply. By enabling two-way communication between utilities and consumers, smart grids empower users to make informed decisions about their energy consumption, ultimately leading to a more sustainable energy future.
