The significance of renewable energy sources lies in their ability to provide sustainable energy without depleting finite resources. Unlike fossil fuels, renewable sources such as solar, wind, and hydro power are continually replenished by natural processes, leading to reduced greenhouse gas emissions and less environmental degradation. Transitioning to renewable energy enhances energy security, creates jobs in new sectors, and fosters technological innovation. Their long-term viability plays a crucial role in mitigating climate change by supporting global efforts towards achieving a low-carbon future.
