Using renewable energy sources such as wind, solar, and hydroelectric power significantly reduces environmental impact compared to non-renewable sources like coal, oil, and natural gas. Renewable energy sources are cleaner because they do not emit harmful pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides, which contribute to air pollution, global warming, and acid rain. Moreover, renewable sources are sustainable and do not deplete natural resources, unlike fossil fuels, which are finite. By relying on renewable energy, we reduce our reliance on environmentally damaging fossil fuels, which helps mitigate climate change and preserve ecosystems, leading to a cleaner and more sustainable future for the planet.
