Energy generation and storage are perhaps two of the most imperative, on-going, and challenging issues facing the world to date. Rapidly growing global energy demands place increasingly greater burdens on the incumbent fossil fuel-based infrastructure. This has resulted in a switch toward both the exploration of new and clean energy sources and the development of highly efficient energy storage devices. Nanomaterials and nanodevices are expected to play a key role in this paradigm shift. However, breakthroughs are needed in our abilities to synthesize nanomaterials and atomistic assembly, to study energy transduction at nanoscale, and to understand the underlying chemical and physical mechanism involved in high-efficient energy conversion and storage. This special issue focuses on the science and engineering of nanomaterials and nanodevices used in all forms of energy harvesting, conversion, storage, and utilization. We solicit research and review papers that address the above-mentioned research topics. Experimental, theoretical, or simulation works are all welcomed. Potential topics include, but are not limited to:

• Nanomaterials for batteries
• Nanomaterials for hydrogen generation and storage
• Nanomaterials for high-performance LED
• Optoelectronic nanomaterials for efficient energy usage
• Photovoltaic cells based on hybrid nanostructures
• Piezoelectric or triboelectric nanogenerators
• Self-powered nanosystems
• Supercapacitors
• Electronic circuits for efficient energy usage
