In order to select the desalination process that is best suited for coupling with solar and wind power on Dhahran area, located on the Eastern Coast of Saudi Arabia, several desalination processes were evaluated and compared with regard to their, energy requirements, technical performances, and economics. Further comparison was made based on the second-law of thermodynamics. Based on this comparison, the reverse osmosis (RO) and multi-effect stack (MES) processes were selected. Three cost-effective designs were proposed. The present value method was used for the economics analysis of these designs. It was found that the augmented solar/wind-powered MES system is economically feasible for desalting seawater with unit distilled water cost ranging between 9.5-15 usd/musd sp3,usd whereas, the autonomous wind-powered RO system is favoured for desalting brackish water with unit distilled water cost ranging between 0.87--1.85 \usd/m.
