Renewable energy is the solution of the growing problems of energy and desalination

Guillermo Zaragoza

The required energy consumption for desalination is a growing matter of concern. The total installed capacity of desalination worldwide exceeds 85.2 Mm3/day. This involves an energy use of at least 100 TWh/year, which is roughly 8.6 Mtoe (to get an idea, this is about 10% the total primary energy consumption in Malaysia and 30% that in Norway). The desalination industry expects the operating capacity to double in the next ten years, which will create serious energy problems. Technical solutions are needed. The reduction of the energy use in desalination has been an objective of research for some time, and in some cases the minimum theoretical work of separation is not too far. But not every effort must be focused on this hard to achieve goal. The incorporation of sustainable energy in desalination is a more attainable alternative that must also be considered, especially due to the geographical coincidence of water deficits with an abundance of renewable energy sources, principally solar and wind energy, but also waste heat from industries..
