A Call for Renewables and Energy Efficiency, page-5

Analysis carried out by PwC for the UAE, that is representative for the region, shows that while there is no
single ‘silver bullet’ today, there are many very promising existing options that could be deployed now or in the near future.
From a water production point of view, one promising area is Reverse Osmosis (RO) technology.

This is economically viable today based on the fact that RO has a far lower energy demand than the current
alternative (Multi Stage Flash, MSF).
Also, if countries in the region look to expand their electricity grid in future with non-thermal and nonwater producing technologies, such as nuclear and solar PV, there will be a greater need for alternative ‘water only’ generation technologies to complement current co-generation and future ‘electricity-only’ plants.
