A Smart Grid is an electricity network that uses digital technology to improve electricity generation, transmission, and distribution efficiency, reliability, and safety. It utilizes two-way communication between consumers and utilities to manage energy usage effectively. This allows for better integrating of renewable sources such as solar or wind into the grid system while providing greater control over energy consumption. Customers can monitor their power use via various devices like smart meters. Additionally, it has allowed new services, such as demand response programs, that help reduce peak loads on the grid when demand is highest. Finally, by increasing efficiency across all aspects of our electric infrastructure, Smart Grids are helping us move towards a cleaner future with fewer emissions from traditional fossil fuel sources like coal or gas plants.
