Smart grids are revolutionizing how cities distribute and consume electricity. Unlike traditional grids, smart systems use sensors, data analytics, and automation to respond dynamically to changes in energy usage, integrate distributed renewable resources like solar and wind, and enhance reliability for urban populations. They can detect outages or energy spikes in real time, automatically reroute power, and facilitate the use of clean energy by balancing loads more effectively. By shifting away from centralized fossil-fuel-based power generation and toward decentralized, clean energy resources, smart grids reduce both greenhouse gas emissions and energy loss. Intelligent metering further empowers consumers, providing them with the data they need to optimize their consumption, decrease costs, and contribute to a greener city environment.
