Energy sources are the various means by which we harness power to perform work or generate electricity. They can be broadly categorized into renewable and non-renewable sources. Renewable sources, such as solar, wind, and hydropower, are sustainable and can be replenished naturally, while non-renewable sources, like coal, oil, and natural gas, are finite and contribute to environmental issues. The shift towards renewable energy sources is crucial for combating climate change and reducing our carbon footprint. By investing in technologies that harness solar and wind energy, we can create a cleaner, more sustainable future. Understanding these energy sources is essential for making informed choices about our energy consumption and environmental impact.
