Nanotechnology in Green Energy Generation

Energy is of great importance in human life because of its benefits as the main resource for human activity. According to International Energy Agency (IEA), energy demands are expected to continue increasing until 2030. Because energy demand will never decrease, it is necessary to develop modern technology, such as nanobased technology, in order to obtain a more effective and efficient process to produce more energy. The application of nano technology or nano material in the field of energy, which involves lithium-ion battery, fuel cell, light emitting diode (LED), ultra-capacitor, and solar cell (including Grätzel cell), is a hot topic in many scientific researches. Unfortunately, its current development is hampered by the expensive cost of production compared to conventional technologies. Therefore, priority should be given to nano technology in the energy sector order to obtain higher efficiency, lower production cost, and easier in its application.

The sustainable energy systems development is among the most essential challenge of the 21 st century. Nanotechnology potentially provides solutions changing of problems related to energy technology, because energy conversion process of practical significance occurs at interface and surface, which are ample in nano structured materials. Materials properties can be particularly modified and combined to produce highly effective, modified, multi-functional materials for quick conversion, storage, and 'consumption' of energy. Additionally, in many manufacturing processes, the use of nanostructure precursor leads to a decrease in the cost, necessary quantity of material, or process temperature, which enables production routes of unrivalled energy efficiency.
