RENEWABLE ENERGY SOURCES FOR SEAWATER DESALINATION

Water and energy are two of the most important topics on the international environment and development agenda. The social and economic health of the modern world depends on sustainable supply of both energy and water. Many areas worldwide that suffer from fresh water shortage are increasingly dependent on desalination as a highly reliable and conventional source of fresh water. So, desalination market has greatly expanded in recent decades and expected to continue in the coming years. The integration of renewable energy resources in desalination and water purification is becoming increasingly attractive. This is justified by the fact that areas of fresh water shortages have plenty of solar energy and these technologies have low operating and maintenance costs.This review paper covers systems, which can be used to harness renewable energy sources; these include solar collectors, photovoltaics, solar ponds, wind energy and geothermal energy and finally talks about some distinguished features of each process .
