Smart grids are intelligent electricity networks that use advanced technologies, such as sensors, communication networks, and data analytics, to optimize the generation, distribution, and consumption of electricity. Clean energy technologies, such as wind, solar, hydro, geothermal, and biomass, are essential for addressing the global energy and climate challenges we face today. The increasing demand for energy, coupled with the need to reduce carbon emissions, has created a pressing need for clean and sustainable energy sources. The development and application of smart grid and clean energy technologies are critical for achieving a sustainable energy future.
