Renewable Energy Sources

Renewable energy sources, such as solar, wind, and hydropower, are becoming increasingly vital as the world seeks sustainable alternatives to fossil fuels. Solar energy harnesses sunlight to generate electricity, while wind power uses turbines to convert wind into usable energy. Hydropower relies on the flow of water to produce electricity, making it a reliable and renewable option. Transitioning to these energy sources not only reduces greenhouse gas emissions but also promotes energy security and economic growth. However, challenges such as initial costs and geographical limitations remain.
