The utilization of conventional energy sources and desalination technologies notably in conjunction with cogeneration plants is still more cost effective than solutions based on only renewable energies and thus is generally the first choice. In closing the world s water demands are rising considerably. Much research has been directed at addressing the challenges in using renewable energy to meet the power needs for desalination plants. Renewable energy technologies are rapidly emerging with the promise of economic and environmental viability for desalination. There is a need to accelerate the development of novel water production systems from renewable energies. These technologies will help to minimize environmental concerns. Our investigation has shown that there is great potential for the use of renewable energy in many parts of the world. Solar wind wave geothermal and even nuclear sources could provide a viable source of energy to power both seawater and the brackish water desalination plants. Finally it must be noted that part of the solution to the world s water shortage is not only to produce more water but also to do it in an environmentally sustainable way and to use less of it. This is a challenge that we should well be able to meet. 7. References Alcocer S. M. and Hiriart G. 2008 . An applied research program on water desalination with renewable energies. Am. J. Environ.
