An Introduction of Water Desalination Exploiting the Waste Heat and Other Different Renewable Source of Energy

The demand for freshwater is increasing exponentially with population, and the scarcity of potable water is also highlighted at various places due to lack of natural reservoirs and irregular rain availability, electricity shortage, and its reach and different factors which contribute to the water shortage in common man’s life, especially for less developed and low-level people living in remote areas who cannot have use of this natural commodity against which they have full right as a human being, so the best method as per the demand is replenishment of this water; many initiatives are being carried out like rain harvesting, proper drainage, but desalination is supposed to be the best among all; this work highlights the desalination process in detail with its necessary components as well as different drawbacks which if reduced can produce this method to be the best among all.
