The Evolution of Renewable Energy: A Path Towards a Sustainable Future I. IntroductionRenewable energy refers to energy derived from natural sources that are replenished at a faster rate than they are consumed. This includes solar, wind, hydro, biomass, and geothermal energy. As the world grapples with the pressing challenges of climate change, the importance of renewable energy has never been more pronounced. Transitioning to renewable energy sources is crucial for reducing greenhouse gas emissions, enhancing energy security, and fostering sustainable economic growth.
