Renewable Energy Integration refers to the process of incorporating energy sources like solar, wind, and hydropower into the existing energy grid. This integration allows for a more sustainable energy supply by reducing reliance on fossil fuels. It involves using technology to manage the variable nature of these energy sources, ensuring a stable and reliable power supply. Effective integration requires advancements in energy storage systems, such as batteries, to store excess energy generated during peak production times. Additionally, smart grid technologies help balance supply and demand, making it easier to distribute renewable energy efficiently across regions.
