Renewable energy generates power through solar, wind, hydro and other cleaner resources. It is essential for reducing emissions, improving energy security and creating a sustainable future. India's renewable-energy market was valued at approximately US$26 billion in 2025, while the global market was around US$1.74 trillion. Future opportunities include solar manufacturing, wind turbines, battery storage, green hydrogen, smart grids and power electronics. Professionals can pursue careers with Indian companies such as Adani Green Energy and Tata Power Renewable Energy, along with global organisations including Vestas, Siemens Gamesa, GE Vernova, Orsted and First Solar.
