From the current issue of the Economist - Utilities in the Middle East: Sun and Sea:
"The main drawback to making fresh water from the sea is that it takes lots of energy. Around 25% of Jordon's electricity and 10% of Israel's goes on treating and transporting water. Using power from the sun could fill a sizable gap, and make Palestinians less dependent on Israeli power. Renewables supply just 2% of Israel's electricity needs, but the government is committed to increasing that share to 17% by 2030. Jordon, which has long relief on oil supplies from Arab benefactors, is striving for 10% by 2030."
