Abstract: Water scarcity is a major problem that needs to be efficiently solved to ensure water availability for future generations. Desalination is an alternative technology for water production based on salt separation from water. However, the energy requirements for that process are high and can be a problem, mainly in isolatedareas. Renewable energy sources are the best way to supply energy needs, because they can be available near the desalination plant, avoiding environmental and availability problems that are associated with fossil fuels. In this paper two forms of renewable energies suited for desalination plant are examined: wind power and wave power. The aim of this study is to present an innovative project which is based on a wind turbine located in afloating platform combined with a wave energy conversion device close to main platform for producing electricity for a desalination plant’s energy needs. The whole project can meet the needs of water demand on islands andit has particular characteristics, as it is floating, autonomous and meets its energy needs in an environmental way, utilizing the wave and wind energy. Also, in the paper the cost and benefits analysis on the unit level is presented, as well as the creation of scenarios to come more closely to real world with regard to implementation of such projects. Also, the requirements of installation, the optimal size of the unit and the weather conditions of installation site are examined.
