Introduction

Population growth, industrialization, and improvement in living quality would lead to further increase in energy demand in near future. Regarding the disadvantages of fossil fuels such as fluctuations in their price, high emissions of greenhouse gases and restriction of their sources, it is crucial to use and exploit alternative energy sources. Energy systems utilizing renewable energy sources such as solar, wind, tidal and geothermal are preferred compared with fossil fuels in terms of emissions, availability and existence in future and reliability. Despite the benefits of renewable and clean energy technologies compared with the conventional systems consuming fossil fuels, their efficiency is still relatively low. In order to make the clean and renewable energy systems economically feasible and attractive for the consumers and users, it is essential to improve their performance and output. Different approaches and techniques have been proposed for performance modification of clean energy technologies in recent decades. Several research works have reported significant potential of nanotechnology in performance improvement of clean energy technologies. With regard to the potential of nanotechnology in performance modification of renewable energy systems and involvement of several factors in the enhancement value, it is necessary to support studies on the relevant subjects. This special issue focuses on the applications of nanotechnology in clean energy systems. Both original and review articles are welcomed to this special for possible publication.
