Abstract

ABSTRACT: Water is the key to preserving earthly life. 71% of the earth area is covered with water; 96, 5% of the world's dirty, unresolved water is contained in the oceans. Water is also found in Earth's fresh-water resources and can be used in rivers and lakes, glaciers and icecaps directly. Water is the key component for the support of Earth life. The salty water ratio of the earth to fresh water. Seventy-one per cent of the land is surrounded by water, and 96.5% of all salty unaccompanied land-water is contained in the oceans. Water can be used directly in rivers, lakes, icecaps and glaciers, also in the world's fresh-water sources. The ratio of salty to fresh water is about 40–1. Nevertheless, population growth and industrialisation led to high fresh water demand for various domestic, agricultural and industrial uses. Fresh water is also very unevenly distributed on Earth. There is now an important problem of the lack of fresh water, which is the only way to achieve marine degradation. The current review paper demonstrates the use of different phase change materials on solar performance.
