Edward Ring of the California Policy Center writes about desalination as a solution for water shortages:

For all its potential, desalination has yet to be a game changer. Worldwide freshwater consumption is estimated at 7.5 billion acre feet per year. Of that total, roughly 20,000 desalination plants worldwide produce an estimated 30 million acre feet of fresh water per year. That’s an awful lot of water, but it’s less than 1 percent of global water consumption.
Nonetheless, desalination plays an outsized role in arid coastal regions around the world. In Israel, for example, five massive desalination plants on the shores of the Mediterranean Sea produce nearly a half-million acre feet of fresh water per year, an amount the nation plans to double by 2030. Israel’s Sorek Desalination Plant, located a few miles south of Tel Aviv, produces 185,000 acre feet of fresh water per year, from a highly automated operation that occupies only about 25 acres. Approximately 80 percent of Israel’s municipal water comes from desalination, and this nation of 9 million people is now exporting surplus water to Jordan.
