Abstract: Water is the key to earthly life maintenance. 71 of the surface of the earth covers water, while the oceans hold 96.5 of the salty, unsolved water of the world. Water can also be used direct in rivers and lakes, Ice-caps and glaciers in freshwater resources on earth. A water is the key element in the maintenance of Earth life. The salty water ratio of the ground to fresh water. 71 of the surface is surrounded by water, and 96,5 of all unaccompanied salty earthwater is contained in oceans. Water can also be used directly in rivers, lakes, icecaps, glaciers in fresh water springs on earth. The ratio of salty to fresh water is about 40 to 1. Population growth and industrialization, however, resulted in high fresh water demands for different domestic, agricultural and industrial applications. Fresh water is also very unevenly distributed on Earth. There is now an important problem of the lack of fresh water, so the only solution is marine desalination. This review paper demonstrates the utilization of different phase-change materials on solar performance.
