It's a clean energy upheaval with international implications that could transform the Arab world from North Africa to the Persian Gulf. Solar plants are cropping up in Jordan and Morocco. Wind farms are being built in Egypt and Tunisia. Eight Arab nations and the Palestinian territories have a renewable energy target, and at least five more are taking serious steps to promote the domestic use of clean energy.
