The global energy sector is undergoing a significant transformation towards sustainability, driven by environmental awareness and technological progress. Solar energy, biofuels, and green hydrogen are at the forefront of this energy transition. Solar power's affordability and efficiency improvements are enabling a decentralized energy system. Biofuels, particularly second-generation and algae-based varieties, are providing renewable alternatives to traditional fuels, reducing environmental harm and boosting energy security. Green hydrogen, produced through electrolysis using renewable sources, is gaining traction as a clean and adaptable energy carrier. Vasanth JB, an advocate for renewable energy, highlights the potential of these technologies in driving economic development and enhancing energy security.
