There are currently more than 16 000 desalination plants worldwide

There are currently more than 16 000 desalination plants worldwide, with a total global operating capacity of roughly 70 million m3 per day. Desalination is the most energy-intensive water treatment technology: desalinated water involves the use of at least 75.2 TWh per year, which is about 0.4% of global electricity consumption. Member countries of the Gulf Cooperation Council (GCC) are among the water poorest in the region, but thanks to their prodigious oil and gas reserves, they have the economic capacity to overcome water scarcity through desalination and to consume water at rates that are among the highest in the world.
