Abstract

As global energy demands increase and climate change intensifies, the transition to renewable energy sources has become a central focus for sustainable development. This article explores key innovations in renewable energy technologies, including solar photovoltaics, wind turbines, bioenergy, and emerging sources like green hydrogen. It also highlights advances in energy storage, smart grid integration, and decentralized power systems. Despite ongoing challenges-such as intermittency, cost, and policy barriers-renewable energy is becoming more efficient, affordable, and scalable. The paper concludes with recommendations for accelerating the global shift to a clean energy future.
