In fact, the swath of desert stretching from the Atlantic Ocean, across North Africa and the Arabian Peninsula, to the Persian Gulf has vast solar potential. Yet only now has a combination of demographic pressure, low oil prices and technological readiness primed Middle Eastern and North African states for more investment in solar power. For countries such as Jordan and Morocco, renewable energy may offer a path toward greater energy independence. Others, such as Saudi Arabia and the United Arab Emirates, are interested in exporting renewable energy technology and financing solar projects abroad....
