Nanotechnology as an Enabling Paradigm for Advancing Sustainable Energy Resources

The global shift toward sustainable and low-carbon energy systems demands technological approaches that simultaneously address efficiency enhancement, scalability, and environmental responsibility. In this context, nanotechnology has emerged as a powerful enabling paradigm by offering precise control over material behavior at the atomic and molecular levels. Such control has led to substantial innovations in energy generation, storage, and utilization technologies. This study critically examines the contribution of nanotechnology to renewable energy systems, focusing on solar photovoltaic technologies, electrochemical energy storage, hydrogen production pathways, and carbon capture mechanisms. Beyond technical advancements, the paper evaluates challenges related to large-scale deployment, environmental safety, and policy integration. The analysis identifies critical research gaps and outlines future research directions essential for doctoral-level investigation and sustainable energy transitions.
