The renewable energy transition refers to the global shift from fossil fuel-based energy systems to sustainable, low-carbon energy sources such as solar, wind, hydro, geothermal, and bioenergy. Driven by the urgent need to reduce greenhouse gas emissions, combat climate change, and ensure long-term energy security, this transition is reshaping the global energy landscape. Renewable technologies offer clean, abundant, and increasingly cost effective alternatives to traditional energy sources, while also reducing air pollution and dependence on finite resources. The transition involves not only technological innovation but also significant changes in energy infrastructure, policy frameworks, and societal behavior. Achieving a just and equitable renewable energy future requires coordinated global efforts, investment in research and development, and inclusive strategies that consider the social, economic, and environmental dimensions of energy access and sustainability.
