“…Thermal desalination such as MSF, MED and VC are energy intensive processes especially in areas with higher water salinity levels such as in the Middle East and GCC countries (35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45) g/L) [41]. Those regions are characterized by abundant solar energy; typical solar radiation ranges from 2200-2400 kWh/m 2 year [42].…”

Despite the tremendous improvements in conventional desalination technologies, its wide use is still limited due primarily to high energy requirements which are currently met with expensive fossil fuels. The use of alternative energy sources is essential to meet the growing demand for water desalination. In the last few decades a lot of effort has being directed in the use of different renewable energy (RE) sources to run desalination processes. However, the expansion of these efforts towards larger scale plants is hampered by several techno-economic challenges. Several medium-scale RE-driven desalination plants have been installed worldwide. Nevertheless, most of these plants are connected to the electrical grid to assure a continuous energy supply for stable operation. Furthermore, RE is mostly used to produce electric power which can be used to run desalination systems. This review paper focusses on an integrated approach in using RE-driven with an emphasis on solar and geothermal desalination technologies. Innovative and sustainable desalination processes which are suitable for integrated RE systems are presented. An assessment of the benefits of these technologies and their limitations are also discussed.

“…The main advantage of the hydropower production is that there is no pollution emerged in the environment because used water falls down in the rivers. It can upgrade quickly with a short interval of time . Hydropower can be stored for long time and can be transmitted from generator to the point of consumption.…”

Summary The economic, social, and environmental aspects are important that should be notable before the selection of a method for the production of energy. Various renewable energy sources are used like hydropower, biomass, biofuel, geothermal energy, and wind energy for the production of sustainable energy that are excellent approaches to fulfill energy environmental energy demands. Renewable sources of energy give an excellent chance to extenuate the gas emission in greenhouse and reduction of global warming with the help of renewable sources of energy. The importance and utilization of the variety of renewable sources of energy are elaborated in this article. The emerging and exploring technique for the production of energy is the photocatalysis. In photocatalysis, solar spectrum is the extraneous source that is used with water to produce hydrogen energy (green energy) by the water splitting under the shower of the solar spectrum. The solar spectrum contains heat and intensity of light from which light spectrum is the abundantly used for the splitting of water. The photocatalyst is the key factor to initiate the reaction depending upon the energy band gap by absorbing the energy from the spectrum of the sun. Semiconducting materials having lower forbidden energy band gap are the basic requirements to use them as a photocatalyst for photocatalysis. Copper vanadate and their composites are the promising materials that are used as photocatalyst for the production of hydrogen energy. Copper vanadate is the focusing material that can be used as photocatalyst. It is an n‐type semiconducting material with 2 eV indirect energy band gap having monoclinic structural phase which is tuned by the doping of metals like chromium, molybdenum, and silver to reduce the grain size and energy band gap and increase the surface area and optical absorption of solar light only to enhance the photocatalytic performance towards the production of hydrogen energy by water splitting in the presence of solar light.

Global water shortages across all continents have led to the explosive practice of desalination. However, desalination is undeniably recognized as one of the most energy‐intensive techniques for creating a clean and safe water supply. Cost reduction in different aspects is necessary to make desalination processes affordable and accessible. In fact, the cost of water from desalination facilities is momentously impacted by the energy requirements for water production. As the water production cost cannot be separated from the issue of energy, the desalination community is continuously seeking ways to reduce energy consumption further. Current research focuses on assessing and alleviating the major energy issues by finding ways to improve the energy efficiency of desalination facilities, which would pave the way for overall cost reduction. Improving the process and the efficiencies of materials implies improved water quality and an increase in the quantity produced per unit of energy consumed. This review highlights recent emerging approaches that aim to reduce the energy consumption and, hence, the water production cost of desalination technology. In brief, the advances made in membrane science and technology, the development of emerging desalination processes and their integrated systems, as well as the use of renewable energy and energy‐recovery systems are recognized as effective and feasible solutions towards energy‐efficient desalination to address the water crisis.
