Energy transition refers to the global shift from fossil fuel-based energy systems to renewable and low-carbon energy sources. This transition involves increasing the use of solar, wind, hydro, and other renewable energies while phasing out coal, oil, and natural gas. It aims to reduce greenhouse gas emissions, enhance energy security, and combat climate change. The energy transition requires technological innovation, policy support, and investment in sustainable infrastructure. It is essential for achieving a sustainable and resilient energy future.
